Options controlling changing conditions:
 +
    -ion_src name current dur lowdisk highdisk lowring highring:
 +
                    have a current source of the specified ion coming in through the specified rings
 +
                    and numdisk (rings and disks are 0-indexed indices, inclusive).
 +
                    Current is in pA for the specified duration (sec).
 +
                    The current is uniformly divided within the entire specified input volume.
 +
                    All -buffer and -ion options must be specified prior to this.
 +
                    See comments by the -time_rate option.
 +
    -ion_src_file name imagename current duration:
 +
                    Similar to -ion_src, but the specified floating point image is used to
 +
                    scale the input current at each voxel. The total current coming into the
 +
                    cell is adjusted so that after this per pixel rescaling, it will = "current".
 +
                    -ion_current_trace with op = S, will modify this.
 +
                    Typically do: int2float -M 1 psf.i2i imagename        prior to this.
 +
    -ion_current_trace name filename dt op threshold:  modifies current specified with
 +
                    the -ion_src or -ion_src_file options.
 +
                    Times which the channel is open (i.e., current flows) is specified in a file.
 +
                    The file is a list of numbers (current or scale), 1 per line, at dt (in sec) intervals.
 +
                    If op = T, currents greater than the specified threshold means channel open, otherwise closed.
 +
                    If op = S, the current as specified with -ion_src is scaled by the number in the list.
 +
                    "threshold" is required but ignored when op = S.  Not extensively tested.
 +
    -zap_sub name time:
 +
                    At the specified time (in seconds) set the named substance concentration
 +
                    to 0. This does not prevent it from being produced from other reactions.
 +
                    This is useful if an injected "ion" was photons (e.g., photon+caged -> uncaged)
 +
                    and the laser is turned off at the specified time.
 +
    -ion_pump name max_rate n k lowdisk highdisk lowring highring:
 +
                    have a pump of the specified ion remove ions in the specified rings
 +
                    and numdisks (rings and disks are 0-indexed indices, inclusive).
 +
                    max_rate * [ion]^n / (k^n + [ion]^n),  [ion] and k in mM. max_rate in mM/sec.
 +
max rates are typically given per unit area (8E-7 umoles/(cm^2 sec) for serca pump).
 +
If we divide these published numbers by the ring width (typically 100 nm) we can get
 +
a rough rate per unit volume.  A typical max_rate might be .1 mM/sec (seems high,
 +
Polito et al. biophysj, May, 2006 give a rate in terms of []/volume of ~ .001 mM/sec
 +
- but they also have a k on the low end, .0001mM, which would compensate some.
 +
  Shuai & Jung, PNAS, Jan. 21,2003, p. 507 have a max rate of .5 (uM?)/sec.)
 +
Typical values for k might be around .0001-.0005 mM. n=2 for serca pump (must be integer)
 +
                    All -buffer and -ion options must be specified prior to this.
 +
    -ion_leak name rate compartment_conc lowdisk highdisk lowring highring:
 +
                    have a leak of the specified ion introduce ions into the specified rings
 +
                    and numdisks (rings and disks are 0-indexed indices, inclusive).
 +
                    rate * ([compartment_conc] - [ion]),  [] in mM. rate in 1/sec.
 +
Leak rates are usually set to exactly balance the pump at initial ion concentrations.
 +
compartment_conc for [ca] in the SR might be around 2 mM.
 +
If max_rate = .001mM/sec, k = .0005mM, compart_conc = 2mM, and resting [ca] = 100nM,
 +
rate should =  .00001923/sec to balance the pump with the leak.
 +
note: Leaks INTO the compartment (when [ion]_in_cyto>compartment_conc) are not allowed.
 +
                    All -buffer and -ion options must be specified prior to this.
 +
 +
Options related to output:
 +
    -save name filename type scale dt:
 +
                    Save images of the specified substance (name) to specified file. By default
 +
                    substances are saved in mM.  This will be multiplied by the scale
 +
                    specified here. dt (in sec) is how often to save images.  Type is I
 +
                    (short int, our normal format) or F (floating pt,2x space, more accurate).
 +
                    The first image saved will be prior to any ion current. The last image
 +
                    will always be the end of the simulation. "name" should be as
 +
                    specified with the -ion, -buffer or -kin option.
 +
                    If the image file already exists, new images will postpended to it.
 +
    -save all tag type scale dt:
 +
                    Equivalent to -save for all ions and buffers. Uses default file names,
 +
                    but adds the tag on the end. ions in nM, all else in uM, then times scale.
 +
    -save_flow name rfilename lfilename scale dt:
 +
                    Save flow images of the specified substance (name) to specified files.
 +
                    rfile is radial flow, lfile is lengthwise flow. Images saved in floating pt.
 +
                    Flow is in pA (1 pA = 3 molecules/usec) times scale.
 +
                    dt (in sec) is how often to save images. 
 +
    -save_flow all ltag rtag scale dt:
 +
                    Equivalent to -save_flow for all ions and buffers. Uses default file names,
 +
                    but adds the tag on the end. Output same scale as above.
 +
                    NOTE: flow for EACH substance takes 8*(number of voxels) of space.
 +
    -debug #:      set debug level to #. May substantially slow down the simulation.
 +
                    1: extra print statements at init. 2: more testing while running. 3:
 +
    -debug_subvolume #: Normally the total mmoles (in the entire cell) of each saved substance is
 +
                    printed to stderr.  Setting this option will also cause the printing of the
 +
                    total over a subvolume. Subvolume is all y >= # (0-indexed).
 +
                    Example: if a cell has patch region at y=[1,10], setting # to the neck (11) of the
 +
                    patch will let you see how much actually gets out into the main part of the cell.
 +
 +
Options related to MPI (multiprocessor stuff):
 +
    invoke on the wolves as, for example,  mpirun -np 3 -machinefile file_of_machine_names cellsim ...
 +
    -print_proc #:  only print output from the specified process (0 indexed).
 +
                  Some output (eg, Total mmoles of ions, etc) are only valid for process 0.
 +
    -overlap #:  overlap neighboring regions by the specified number of voxels (default = 50)
 +
                  This will also be the number of iterations between necessary synchronization.
 +
    -debug_mpi #:  print MPI info. Execute MPI dummy stubs if MPI NOT present (eg, under Windows,SGI).
 +
                  This version of the executable does NOT use MPI.
 +
    -debug_mpi_proc rank numproc:  set dummy rank and number of processes. use only if MPI NOT present!
 +

===  channel_current2  ===
 +
<nowiki>
 +
channel_current2: like channel_current, but looks at [ca] over time at each BK (not just max [ca]).
 +
From that, it calculates the max BK current. Channel_current adds the max [ca] that each BK voxel sees
 +
from each voxel in a Ryr cluster, to get the max [ca] that BK pixel sees.  But the max [ca] could occur
 +
at different times since the Ryr cluster has a spatial extent.  Experimental.
 +
 +
Calculates the current which would be produced when each object in Ryr_image.i2i releases calcium which
 +
activates nearby BK channels in BK_image.i2i. Produces a histogram of these output currents.
 +
The input images should have each pixel in an object having the object id as its value. These images can be
 +
produced with "countobjs -Q" or "objs_via_ascent" 
 +
note:  a one pixel border around the image is ignored (added 12/8/09).
 +
This may take about one-half hour to run.
 +
 +
Usage:
 +
channel_current [options] -f filename Ryr_image.i2i BK_image.i2i > im1_im2.hist
 +
Options:
 +
-f filename resting: file containing [ca], in nM, as a function of distance and time. Right now this is
 +
assumed to have 20 nm spacing and entries every msec. See
 +
/home/lml/krypton/Zhuge/STIC/simulations/run32.ca as an example
 +
"resting" is the resting [ca], in nM, for the cell. It will we subtracted from the other
 +
[ca] values to produce a "delta" [ca] which gets scaled linearly by Ryr intensity.
 +
The spark current used to produce this (see -C) should be roughly in the range expected
 +
for Ryr_image.i2i, since all delta [ca] is linearly extrapolated.
 +
All distances > largest distance in filename will have their [ca] set to the [ca]
 +
at the largest distance in filename.
 +
note: Only the [ca] values at y == 1 are used. Is this what should be used?
 +
-u #: voltage (mV).  BK conductance is a function of voltage. default = -80.000000
 +
-U low delta hi: voltages from low to hi by delta. Max is 20 voltages
 +
-r #:         resolution (binsize) for output histogram in femtoAmps, default = 1000.000000
 +
-R #: reveral potential of BK channel in mV, default = -80.000000
 +
 +
  distances:
 +
-w # # #: x,y, zweights for pixel distances (ie, pixel size), default = 1 for each.
 +
-p #: pixel size in nm (i.e., what 1 means in -w option), default = 80.000000
 +
-m # :         maxdistance (in units used for -w, i.e., pixels) to look for the closest pixel, default = 10.000000
 +
 +
  which pixels or clusters to include:
 +
-t # #: image1 and image2 thresholds, pixels > # are above threshold, default = 0.
 +
-e lowx lowy lowz hix hiy hiz:  only look at voxels within this extent (subvolume), 1-indexed, inclusive.
 +
-s minsize maxsize:    only look at objects in Ryr_image.i2i within the size range (inclusive, in voxels)
 +
max size allowed = 100000
 +
-S minsize maxsize:    only look at objects in BK_image.i2i within the size range (inclusive, in voxels)
 +
-i miniod maxiod:    only look at objects in Ryr_image.i2i within the iod range (inclusive. use -d also.)
 +
-I miniod maxiod:    only look at objects in BK_image.i2i within the iod range (inclusive. use -D also.)
 +
 +
  scale factors:
 +
-d Ryrimage1d.i2i #: the original intensity image for Ryr_image (since Ryr_image has pixel values as id numbers)
 +
# is the number of Ryrimage1d.i2i intensity units required to produce spark current
 +
used in the calcium simulation (which produced the -f filename data).
 +
This will scale the [ca] produced by each Ryr voxel. Default = 30000.000000
 +
-D BKimage2d.i2i #: the original intensity image for BK_image (since BK_image has pixel values as id numbers)
 +
# is the BKimage2d.i2i intensity from one BK channel.
 +
This will scale current produced. Default = 1000.000000
 +
If you want the intensity of each Ryr or BK object to affect the ca release (for Ryr)
 +
or number of channels (for BK) , you need to provide the original data by using the
 +
-d and -D options. Otherwise all voxels in an object contribute equally (so large objects
 +
have more receptors or channels than small ones).
 +
-c #: BK single channel conductance in pS, default = 220.0
 +
-C #: peak current (in pAmps) used in the simulation to produce -f filename, default = 1.000000
 +
This is just used for output produced by -v to estimate spark current produced per Ryr cluster.
 +
 +
  miscellaneous:
 +
  -v: verbose. produces list of each Ryr cluster and K current produced to stderr. Other stuff too.
 +
To write this to a separate file do: (channel_current -v ... > stdout.channel) >& stderr.channel
 +
  -V: very verbose
 +
 +
Examples:
 +
 +
cellsim -spacing /home/lml/krypton/Zhuge/STIC/simulations/spacing2.txt ....     : produces ca.i2i
 +
printvalsL -spacing2.txt -R -t -i ca.i2i > ca.vals

 +
      objs_via_ascent -s 5 100 Ryr.i2i Ryrid.i2i > tmp
 +
tail tmp  : the mean IOD gives an idea of brightness needed to produce current used in cellsim, say 30000
 +
      objs_via_ascent -s 5 100 BK.i2i BKid.i2i > tmp
 +
tail tmp  : the mean IOD gives an idea of brightness of a BK cluster, eg mean= 10000, but assume that's 10 channels

===  cluster  ===
 +
<nowiki>
 +
Drops random Ryr receptors into a world.  Then calculates how many clusters and their sizes get produced.
 +
Currently the "world" default size is  (2um)^3.  (see -wsize)
 +
The origin of this world is in it's center (so it goes from -1um to +1 um in each direction by default).
 +
A histogram of cluster sizes is printed to stdout.
 +
 +
Usage:
 +
cluster [options]
 +
Options:
 +
distance options:
 +
-eucliddist:      calculate a Euclidean distance (same in x,y,z directions). This is the default.
 +
  (use -cdist option to set the nearby distance for this).
 +
-absdist:   rather than calculate a real distance, calculate max(ABS(dx),ABS(dy),ABS(dz)) - for speed
 +
  (use -cdist to set the nearby distance for this.)
 +
-psfdist x y z:  distance (in um) a pt can be in the x, y, and z directions and be considered nearby.
 +
  Does not use -cdist.  To approximate a psf you might specify .2 .2 .6
 +
      -cdist #:        how close (in um) two receptors must be to cluster, default = 0.500000
 +
other options:
 +
      -2D:   do a 2D simulation (x and y), not a 3D simulation
 +
-cylinder inner outer:  only place Ryr within a cylinder (e.g., plasma membrane) with specified
 +
                        inner and outer radius (in um). The cylinder has its length the entire y dimension.
 +
  Only the parts of the cylinder which fit in the world (-wsize) are used.
 +
-wsize x y z:   the width of the world (in um) in the x, y, and z directions (default = 2.0,2.0,2.0)
 +
-psize x y z:   pixel width (in um) in the x, y, and z directions (default = 0.1,0.1,0.1)
 +
      -numryr #:        number of Ryr receptors to drop, default = 1000
 +
-mindist #:   when placing Ryr receptors, keep this minimum distance (in um) between them.
 +
-randstart #:   start the random number generator with # as the seed. So runs can be reproduced.
 +
-image name.i2i   write out an image of the Ryr receptors.  Can then use blur3d to create a realistic
 +
  microscope image, and countobjs to analyze it and compare to real data.

/home/lml/krypton/bin/makebeads2
 +
 +
randomly distributes beads within a volume.  created to let Jack simulate
 +
distribution of glut4 labels vesicles in the TIRF field of a microscope.
 +
A bead has a constant value between its inner and outer diameters. This value
 +
falls to zero 3 standard deviations inside the inner diameter and 3 sd outside
 +
the outer diameter. Beads are not allowed to intersect each other.
 +
Writes info about beads created or moved to stdout (can be read back in with -b option).
 +
note: coords written out are zero indexed (not 1-indexed like addlines and play) in pixels.
 +
usage:
 +
makebeads2 [options] outimage.i2i
 +
options:
 +
-d x y z: image dimensions in pixels, default = (256,256,64)
 +
-D # #: bead inner and outer diameters in microns, default = 0.200000 and 0.200000
 +
-R #: inner rise standard deviation (in microns), default = 0.012500
 +
-F #: outer fall standard deviation (in microns), default = 0.012500
 +
-S x y z: x, y, and z pixel dimensions (in microns), default = (0.040000,0.040000,0.010000)
 +
-c x y z: x, y, and z pixel dimensions for new image size.  If you are planning on taking the
 +
image produced by makebeads2 and using chres to change pixel size, put the new
 +
pixel sizes here. This is used when calculating the intensity of the brightest pixel
 +
from each bead. This output info can be useful for signal to noise ratio tests.
 +
-X #: number of subpixels per pixels, default = 10
 +
-p # val: set z plane # (0 indexed) to val (modelling diffuse fluorescence on the plasma membrane)
 +
If val is < 1 it is interpreted as a fraction of total light in the image.
 +
For example: val = .2 means set the z plane to the intensity necessary so that the total
 +
light in that plane is 2012f the total in the final image (i.e., after exponential if -e or -E)
 +
-e dist: apply an exponential scale factor exp(-z/dist) to each zslice; like a TIRF excitation intensity
 +
dist is the 1/e distance in microns (.1 is a good value)
 +
This exponential also get applied to z plane value set via "-p # val" if val >= 1. It does
 +
NOT apply to that if val < 1.
 +
-E amp2 dist2:apply a second an exponential scale factor amp2*exp(-z/dist2) to each zslice
 +
must also use -e option.  Each intensity will be scaled by (amp1*exp(-z/dist)+amp2*exp(-z/dist2)).
 +
amp1 + amp2 = 1 and is automatically set when -E is used (amp1 = 1-amp2).
 +
 +
options related to output:
 +
-i #: outimage.i2i should be scaled by # before writing it.  Format is short int (our default format).
 +
-f #: outimage.i2i should be scaled by # before writing it.  Format is float.
 +
-v: verbose.
 +
-A: don't create outimage.i2i (still need a dummy name on command line though).
 +
-B: don't even simulate voxels (just prints beads centers, amplitudes, sizes).  Automatically sets -A.
 +
-u file.objs: create file, which has a list of bead objects created, in the same format countobjs produces.
 +
this lets utilities written to analyze files in that format to then be used
 +
(e.g., objs2dist.pl, objs2bb.pl). COM field is the bead center even if part of it is outside
 +
the image. Size field is in pixels (only counting what is within the image).
 +
IOD is the total bead light in the image after exponential weighting (if -e or -E) and scaling (-i, -f).
 +
AVG = IOD/size.  MAX is the max pixel (after -e,-E,-i,-f) . Some file header info may be wrong.
 +
-U file.objs: like -u, but all z coords are replaced by 1, and coordinates are for the new resolution specified
 +
by -c option. MAX value and max coord come from a sum projection in z at the new resolution.
 +
(after -e,-E,-i,-f).
 +
-W: print some warning messages to stderr if appropriate.  note: This will mess up the output in the file
 +
if you are running it as:  makebeads2 -W .... >& file.out
 +
 +
options controlling randomization (of a uniform random distribution unless otherwise noted):
 +
-s min max: mininum and maximum range of allowed bead sizes. This number scales the
 +
bead inner and outer diameters (does not change sd). default = 1.000000 and 1.000000
 +
-G mean sd:  make bead sizes (scales) a Gaussian variable with specified mean and sd (instead of -s).
 +
note: since beads can't intersect, if you place beads densely you will tend to get more
 +
small beads (since the program generates a new random bead if one doesn't fit), and hence
 +
the size distribution will no longer match the parameters specified here.
 +
-g mean sd shell: like -G, but also specify bead shell thickness in microns.  mean doesn't scale the shell thickness.
 +
mean is the diameter to midway between the inner and outer diameters (so don't use -D option).
 +
-a min max: min and max amplitude (brightness) of bead, default = 1000.000000 and 1000.000000
 +
a pixel which is entirely covered by the shell of the bead (between -D numbers) will have this value.
 +
So this is like specifying a fluorescent concentration.
 +
-P lambda scale:  make amplitude a Poisson variable with the specified mean (lambda) value (instead of -a option).
 +
this value then gets multiplied by scale.  Amplitudes of 0 get ignored (a new amplitude is calculated).
 +
note: this is still just the amplitude of a covered pixel, not of the entire bead unless -T used too.
 +
-T: The amplitude specified with -a or -P option is the total light in the bead, not the light
 +
of one fully covered pixel.  Takes about double the time to run.
 +
note: if the amplitude isn't large compared to number of pixels in the bead's shell, then
 +
individual pixel intensities will be small and truncation may effect total intensity.
 +
-x min max:  allowed position of beads, in pixels, zero indexed, inclusive. The entire bead must fit in this region
 +
unless -o option also specified.
 +
-y min max:  allowed position of beads, in pixels, zero indexed (default = anywhere within image)
 +
-z min max:  allowed position of beads, in pixels, zero indexed (default = anywhere within image)
 +
-o: allow bead centers to fall outside the image volume (except in low z direction, i.e. coverslip).
 +
This is a more accurate way to represent a small view of a large cell.
 +
This option is ignored if -b option used.
 +
-O: like -o, but beads in low z direction outside the volume reflect back inside the volume (i.e. get
 +
moved back inside volume instead of thrown away).
 +
note: if bead density is too high, reflecting a bead inside may cause it to intersect with a previous
 +
bead, in which case the reflecting bead will be thrown away and a new randomly placed bead created.
 +
-w #: use # as the seed for random number generator, so can reproduce exact runs. must be negative.
 +
-b file xyspeed zspeed:  read initial bead params (e.g., size, position) from file, just add random position to this.
 +
the random position uses the speeds (in microns) as the max the vesicle can move in each direction
 +
in this time period (i.e., dx = ran(0 to 1)*xyspeed, etc).
 +
Set xyspeed and zspeed = 0 if you don't want to move the beads.
 +
  -j #: long int starting seed for random number generator. specify the same number (not 0) each time you run this
 +
program if you want to exactly repeat the random numbers generated. The default is to use a different
 +
starting seed each time based upon the process id when you run the program.
 +
-n #: number of beads to make, default = 100, max = 10000
 +
 +
Examples:

#create 200 beads, with a 50 nm (5 z plane) gap before the pm, which has an

===  oxygen  ===

<nowiki>
 +
Calculates steady state partial oxygen pressure (P) as a function of distance from a blood vessel (r).
 +
The blood vessel has a radius of R1 (5.0 um) and Oxygen at the vessel is Ps (52.0 mm Hg).
 +
The default is to print partial Oxygen pressure (mm Hg) as a function of distance (um) as columns to stdout.
 +
All models set P at R1 (and r<R1) to Ps. All models clamp P at R1 to be Ps for all time (vessels stay oxygenated).
 +
 +
The line source model (-m 1) implements equation 17 from KroghOxygenDiffusionModel1.pdf
 +
  Modeling pO2 Distributions in the Bone Marrow Hematopoietic Compartment.
 +
  I. Krogh's Model  by D.C.Chow, L. A. Wenning, W. M. Miller, and E.T. Papoutsakis
 +
  Biophysical Journal, vol. 81, August 2001, pp. 675-684.
 +
This models O2 assuming a constant oxygen consumption by the tissue and constant O2 (Ps) at the blood vessel.
 +
They claim results don't change by more than a few percent using proportional (or other) O2 consumption models.
 +
The value of dP/dr at R2 is forced to 0.
 +
note: this is an implmentation of O2 from a line source (e.g., blood vessel), not a point source.
 +
So it is not appropriate to convolve (in 3D) this with a 3D image of blood vessels.
 +
But -p (or -m 2) will produce a point source image.
 +
 +
The point source model (-m 2) implements equation 14 from HeatConduction.pdf
 +
  Steady Heat Conduction in Layered Mediums: The Half-Space and Sphere, by Henry N. Pollack
 +
  J. of Geophysical Research, vol. 70(22), Nov. 15, 1965, pp. 5645-5648
 +
This models O2 assuming a constant oxygen consumption by the tissue and constant O2 (Ps) at the blood vessel.
 +
note: The value of dP/dr at R2 is forced to 0 unless -b # is specified.
 +
note: Since O2 consumption is constant, it might not make sense to use this in a convolution, since it isn't
 +
      linear.
 +
 +
Model 3 is a point source model, but O2 consumption by the tissue is proportional to the O2 level in the tissue.
 +
  I derived it from Crank's equations 6.60 (infinite hollow sphere model) and 14.13 (see below).
 +
  It requires the specification of an initial O2 level in the tissue (P0, which is the same everywhere).
 +
  R2 is used only to determine how far out to plot the graph (and dP/dr at R2 is not used either).
 +
  See my paper notes or ~/krypton/Corvera/Olga/SteadyStatePointDiffusion.pdf
 +
  Not only is proportional O2 consumption more biological, but I think this should be linear and therefore
 +
  it makes more sense to use in a convolution with a (binarized?) blood vessel image.
 +
 +
note: because R2 really should vary in an image, depending upon the distance between nearby blood vessels
 +
        and because Ps is not just a scale factor (so, eg, brighter blood vessels in an image, if brightness is
 +
        proportional to Ps, do NOT just cause a scale factor in the P(r) values), it may NOT be appropriate
 +
to take the image produced by this program and convolve it with an image of blood vessels to get
 +
estimates of oxygenation of tissue. This comment may apply to all three models (definitely to -m 1)
 +
 +
Usage: oxygen -m # [options] 
 +
    required:
 +
  -m # which model to use.
 +
        -m 1 :line source model with constant O2 consumption
 +
-m 2: point source model with constant O2 consumption.
 +
        -m 3 :point source model with O2 consumption proportional to O2 concentration.
 +
Use point source models if planning on convolving resulting image with a blood vessel image.
 +
 +
    options for all models:
 +
Although these options can be used in all models, different models have different sensitivities to them.
 +
  -R1 # vessel radius (um). Changes to this can change P a lot (if -m 1), and may require R2 to change (see -c).
 +
default = 5.00
 +
  -R2 # max distance any tissue is from a vessel (um). This changes the solution a lot for some models
 +
but for the -m 3 model it only affects how far out data is graphed, default = 2268.00
 +
More precisely, for -m 1 and -m 2 it is the distance at which dP/dr = 0 (ie, a b.c. on the pde).
 +
  -Ps # partial pressure of Oxygen at the blood vessel (mm Hg). Default = 52.00
 +
40 is typical of veins, 95 of arteries. This is held constant over time in all the models right now.
 +
For -m 1, this will affect the O2 value at R1, but how P changes RELATIVE to P(at R1) (as r increases)
 +
will not be affected (ie, it does NOT just scale everything).
 +
    model 1 options:
 +
  -c use with -R1 to automatically calculate R2 based on the specified R1 (since R2 affects the solution).
 +
(this also sets -m 1 as a convenience)
 +
    model 2 options:
 +
  -b # changes the 2nd boundary condition to be P at R2 = # mm Hg
 +
instead of dP/dr = 0 at R2 (this also sets -m 2 as a convenience)
 +
    model 3 options:
 +
  -P0 # the initial oxygenation level of the tissue (mm Hg). Default = 0.000000
 +
This will change the solution a lot, since it is also the level that O2, in steady state, approaches as r->infinity.
 +
Therefore, nonzero P0 may also make convolution with a blood vessel image inappropriate.
 +
-P0 0 seems to produce the same results as -r. (-P0 also sets -m 3 as a convenience)
 +
 +
    output graph options:
 +
  -n normalize output (doesn't affect -i image.i2i), ie, print r/R1  vs P/Ps  rather than r vs. P
 +
  -r add a third reference column which is the "simple" diffusion solution (goes as 1/r)
 +
This is for a point source in 3D (not a line source), and ignores O2 consumption.
 +
graph as: oxygen_krogh -r | xmgr -nxy stdin
 +
 +
    output image options:
 +
  -i image.i2i xdim ydim zdim:  create an image of the values, to use with blur3d to find
 +
O2 everywhere in an image as a function of distance from blood vessels.
 +

#/home/lml/krypton/bin/total_ca
 +
 +
Reads in a floating point image or short int image as produced by simulation (i.e., cylindrical coords), calculates
 +
the total calcium change (i.e., [ca](r)*pi*r*r - t(0)) as a function of distance from the calcium entry site.
 +
Output is printed to stdout.
 +
All input concentrations should be in nM
 +
Each z slice is analyzed separately (i.e., z is assumed to be time) unless image is rectangular and 3D (-R).
 +
 +
Usage: total_ca [options] ca.i2i
 +
      options for printing graphs of calcium (not concentration) vs. distance from ca entry location:
 +
the units for the graph are nM*um^3, but 1nM = .6ions/um^3 , so multiply be .6 to get ions
 +
                      (and 1pA = 3,000 ions/msec if you want to convert to pA-msec).
 +
        -n: normalize calcium distance graph for each z slice (so sum of amplitudes = 1),
 +
                      (otherwise when graph spacing is changed, -g option, the height of the graph will change).
 +
  -a:    print absolute calcium, not delta calcium (the default).
 +
                      when this is applied to a uniform image it should produce a 4pi*r*r distribution.
 +
            The default, delta calcium, prints the delta (i.e., change) from slice 0 (regardless -z option)
 +
        (but delta calcium not calculated if 3D rectangular, i.e., -R specified).
 +
 +
  -p # #: pixel size in microns in the radial (x) and lengthwise (y) directions,
 +
default =  0.10 and  0.10
 +
  -P # # #: pixel size in microns in x,y,z directions (rectangular not cylindrical coords),
 +
default = ( 0.10, 0.10, 0.10)
 +
  -r: data is rectangular, not cylindrical coords (-P sets this too)
 +
(e.g., already passed through cyl2cart).
 +
  -R: data is 3D rectangular (not 2D+time), not cylindrical coords.
 +
  -e x y:      0-indexed coords of calcium entry location (default: x= 0, y = ydim/2)
 +
  -E x y x:    0-indexed coords of calcium entry location for 3D rectangular data
 +
(i.e., z direction is not time). sets -R option.
 +
        -g #: graph spacing. default is the pixel size.
 +
        -s #:        subsample each voxel this number of times in the x (radial) and y (longitudinal) directions,
 +
                      (and z if 3D and not 2D+time) default = 3 (anything less tends to introduce errors).
 +
        -z low hi dz: only look at z slices low to hi (0-indexed, inclusive), stepping by dz.

===  vcspat-models  ===
 +
<nowiki>
 +
argc = 1
 +
 +
This program creates a volume image with objects randomly placed
 +
within it.  The mask image defines where an object is allowed to be placed.
 +
The mask value can be changed with the -M option.  Objects can either be individual
 +
voxels (the default) or tiny images (-o option) or connected voxels in an image (-O).
 +
 +
Usage:
 +
  vcspat-models [options] mask.i2i out.i2i
 +
 +
Options:
 +
  -m #    : model number (default 0).
 +
            0 - grid pattern
 +
            1 - random pattern
 +
  -M #    : value of mask pixels (default 1).
 +
  -r #    : number of random points to use in random pattern (default 25000)
 +
  -o name  : image to use at point in pattern (default just turns on a pixel)
 +
(can use up to 256 images - image will be randomly chosen)
 +
  -a : if objects overlap, add their pixel values instead of just replacing
 +
 +
Options related to objects:
 +
  -O thresh name.i2i: threshold an image to use for objects. Extracts as an object each
 +
            connected set of voxels above threshold.  Places these  objects randomly
 +
            into the output image (uses each object once). Use with the
 +
            -m 1 option. Do not use the -r option
 +
  -P name.i2i id.i2i: similar to -O option, extracts as an object each of the
 +
    the objects in name.i2i based upon their pixel values (object id) in id.i2i
 +
(e.g., id.i2i was produced via objs_via_ascent). This option preserves the
 +
distinction between objects in name.i2i which may be touching - since simple thresholding is not used.
 +
If only an id.i2i is available (no name.i2i), you can specify -P id.i2i id.i2i
 +
  -v: replace objects (after fitting them into the image) with just the single voxel
 +
at the brightest location in the object.  Only use with -O and -e options.
 +
  -S # #:  minimum and maximum object sizes to allow (use with -O option).
 +
  -e: do not allow (exclude) objects to be placed so that they overlap with each
 +
other, go outside the image, or go outside the mask.  The default is to allow
 +
overlaps and to just zero out that part of an object which goes outside the
 +
image volume or mask.
 +
  -n: number the objects in out.i2i (use with -O or -P options). Rather than all
 +
the pixels in an object being their original values, all the pixels in object 1
 +
will be labeled 1, all those in object 2 labeled 2, etc.  If -e not specied and
 +
objects overlap the first object placed (usually the largest) will prevail.
 +
Can also be used with -v, then output will have the brightest voxel set to object id, others to 0.
 +
The output of this can be analyzed by object_overlap program.
 +
  -N out2.i2i:  create a second output file, number the objects in out2.i2i (like -n).
 +
 +
OtherOptions
 +
  -s #    : seed for random number generator (default pid)
 +
  -x #    : x increment for grid pattern (default 3)
 +
  -y #    : y increment for grid pattern (default 3)
 +
  -z #    : z increment for grid pattern (default 3)
 +
  -V: verbose
 +
 +
note: entire image name (with extension) is required.
 +
note: a - in place of an image name means stdin or stdout.

 +
<nowiki>
 +
 +
Takes a 3d image and an outline and keeps all data pts within the specified distance
 +
of the outline (removes the "core" of the cell). 
 +
Also produces a file named in_image_H.histo. See help for histogram2 about that.
 +
If in_image2.i2i out_image2.i2i are specied, in_image2.i2i is also cored
 +
(and histogram2 is applied to the pair in_image.i2i and in_image2.i2i when producing in_image_H.histo).
 +
 +
Written to let Ronghua only keep BK and Ryanodine label near the plasma membrane.
 +
Note: touching voxels may have a distance of .5 voxels, and voxels at the same
 +
      position may have a distance of -.5 (??)
 +
Note: pixels may be kept near the end of the cell, since they have close distance to the end
 +
      (rather than to the plasma membrane. Might -Z # # option to histogram2 fix this?).
 +
Note: there might be problems if boundary.pts touches the edge of the image.
 +
 +
 +
Corecell.pl [options] in_image.i2i boundary.pts out_image.i2i [in_image2.i2i out_image2.i2i]
 +
 +
options:
 +
-interp interpolate missing z slices in boundary.pts before using it.
 +
zslices must be in ascending order in boundary.pts.
 +
contours must all be drawn in the same direction (i.e., all clockwise or all counter-clockwise).
 +
The name of each object is changed to "nuke".  A maximum of 1000 zslices is allowed.
 +
-shrink=#  shrink boundary.pts by this number of pixels before using it
 +
-expand=#  expand boundary.pts by this number of pixels before using it
 +
-zrange=#:#    only examine z slices (1-indexed in this range)

-dist=#: keep all voxels within this distance of the boundary, default = 2

-dy=#          pixel size y size (although if you change this then that may affect -dist)
 +
-dz=#          pixel size z size
 +
-dontcapends    first and last outline slices aren't capped (removes -c from the call to histogram2).
 +
        typically you'd use this if the outlines are circular cross-sections of a cylindrical
 +
cell (ie, z is along the length of the cell).  If the outlines are along the length
 +
of the cell (ie, cell is in the xy plane, as Jeff likes to do), then you wouldn't use this option.

  mask_gedmat_images4.pl  -check_intersect  added.
 +
determines when outlines intersect and sets the aerr (area error flag) in the
 +
output file. eventually it will calculate areas a different way when that happens
 +
rather than combining masked images (see ~/krypton/Corvera/Raz/README for 10/18/13). not done yet ...
 +
 +
  Examines all the zip files (produced within fiji when outlining regions) in the current directory. These have
 +
  the boundary of the explant, day7 growth, and day11 growth.
 +
  note: this program assumes that all the data in the directory is from the same patient and the same tissue type.
 +
 
 +
  It recalculates the area measures by only including that part of the day7 and day11 growth which is between the explant
 +
  center and going towards the center of the well; area from the explant center going away from the center of the
 +
  well (ie, growing towards the well wall) is excluded. By doing this, we hope to minimize the
 +
  effect of growth (as measured by area) being stopped by the well wall when the explant is near the well wall. 
 +
  Output is written to stdout. The comments there explain the fields. area_mex is the old value, area_mex_border is the new.
 +
 +
  This is done by finding all the *_Area.zip files in the current directory, pulling out the outlines in those files
 +
  and using that information to recalculate areas.  It also needs to find the associated "combined" image file
 +
  (*_combined.i2i) to get image size and hence the position of the center of the well) and the fiji results file
 +
  (*_results.txt, so the numbers produced here can be easily compared with them).
 +
 +
  note: The algorithm assumes that the area NEVER DECREASES with time, and that the explant region is always surrounded
 +
by the day7 region which is surrounded by the day11 region. The latter assumption is sometimes invalid if
 +
the day 11 images were shifted relative to day 7 images; but that is usually ok.
 +
(if necessary, you can manually change the "bad_data" field in the output file to 1 and then use
 +
-cond in gedmat_to_xy.pl to eliminate those stats from further analysis.)
 +
It also assumes the smallest area in each zip file is the original explant area, the next largest area is
 +
called day7 area and the largest area (if 3 are present) is assumed to be day 11 area.
 +
Sometimes when growth is about 0, the outlines on, eg, day7, may have slightly less area than the original
 +
explant, so the outlines might be mis-ordered then. [actually it may read the correct day off the name of
 +
the i2i image now].
 +
 +
  note: If only 2 areas (ie, two .roi files) are present in the zip file, they are assumed to be for
 +
the explant and day7 (not day11).
 +
 +
  note: This program assumes the center of the combined image (usually 4 well images are combined into one) is the
 +
center of the well. see combine_images.pl. It also assumes the combined image name ends in combined.i2i
 +
(see -combined).
 +
 +
  note: some of the scripts I use to then analyze these results will multiply the area by 2, to get a "true" estimate
 +
  of growth; since the value produced by mask_gedmat_images3.pl will be (roughly) half of the real growth rates.
 +
 +
  usage:
 +
mask_gedmat_images3.pl  [options]
 +
 +
  options:
 +
-tmpdir=fullpathname directory to use for temporary files which are created, eg: -tmpdir=/home/lml/krypton
 +
 +
-zip_file=file.zip
 +
-zip_file=file.zip:file2.zip:...:filen.zip
 +
only examine the one specified zip file, not all those in the directory
 +
(If the second form is used, you can specify as many as you want.)
 +
note: you may still need to specify -zip_ending so that the ending of this file can be stripped
 +
      off correctly (so the -combined_ending and -results_ending can then be added correctly).
 +
-zip_ending=stuff e.g., -zipending=_area.zip  .  All files which end in this will be analyzed; default = _Area.zip
 +
-skip=file.zip[:file2.zip...]  list of zip files (without the full path) to skip.
 +
 +
-results_ending=stuff e.g., -results_ending=_results.txt  .  This is what the -zip_ending should be replaced by
 +
to get the name of the associated fiji results file.  note the _ should be included here
 +
if it was included in -zip_ending.
 +
 +
-combined_ending=stuff  e.g., -combined_ending=_combined_reduced_.i2i  . default = combined.i2i.
 +
This is any string which helps identify the last part of the combined image filename.
 +
-combined_scaling=#:# e.g., -combined_scaling=2:2 if reduceima -bin 2 2 was applied to get _combined_reduced_.i2i.
 +
 +
-scale=#:# distance and area (eg, -scale=2:4 if reduceima -bin 2 2 was used) scaling. This will multiply
 +
the area stored in the fiji file and the area calculated via my mask by the second number.
 +
The first number will multiply the distance of the explant from the center of the image.
 +
This option is just here to handle 001_BAP and 002_PRO datasets. They were analyzed in fiji
 +
with the images reduced by a factor of 2 in x and y. So the fiji areas produced will be low
 +
by 4x, as will my areas.  This option compensates for that.  See ~/Corvera/Raz/README for 10/11/13.
 +
 +
-check_intersect check if outlines intersect with the explant's outline. If so, set an error flag on stdout printout
 +
and print info to stderr.  eventually will just use area numbers rather than masking area in this situation.
 +
that is not done yet ...
 +
 +
 +
-save_day[=directory]
 +
saves the final binary mask for each days growth (eg, day7 growth minus the explant and minus the part growing towards the wall)
 +
into a 3d mask image (patientid_tissue_day#_mask.i2i).  This image will be reduced down in xdim and ydim from the
 +
original.  patientid_tissue_day#_.play_labels will also be created (labels which well each z slice comes from).
 +
This is mostly for quality control purposes.
 +
In addition, patientid_tissue_day#.rpts will be created (similarly reduced down in size) (coords may be off by 1?).
 +
View the file via: addlines maskim.i2i maskim.rpts -  |play.FC14 -P -1 R -labels maskim.play_labels -
 +
  or via: play_results3.pl
 +
patientid_tissue_day#_orig.i2i will be the original images (also reduced in xdim and ydim, and only one 2d slice
 +
from each original 3d image).
 +
note: older versions of play may need the comment line at the top of maskim.play_labels removed.
 +
note: if you want images to be in another directory, specify a full pathname, eg -save_day=/home/lml/krypton (without last /).
 +
note: any existing file with these names will be OVER-WRITTEN.
 +
note: this option creates lots of temporary files (in tmpdir) of the form __*.i2i, any existing
 +
      files that match this will be DELETED.
 +
see also: montage
 +
 +
-just_check just check whether each zip roi outline has the correct number of associated image files.
 +
eg, if the zip file has 3 outlines (explant, firstday, secondday) there should be two i2i files with DAY# in their name.
 +
prints to stderr info about those which don't have the correct number. does nothing else.
 +
-verbose some extra info to stdout
 +
-debug prints some tracing info to stderr
 +
-print_fname print name of each zip file as it is being analyzed, to stderr.
 +
-dlevel=# extra debugging. the bigger the number the more the printout. # is an integer starting at 1.
 +
-dlevel=1 will print a trace of commands to execute to mimic (parts of) this perl script.
 +
-noclean don't remove the temporary files which were created
 +
the files are: _ones.i2i _explant.rpts _day11.rpts _day7.rpts _excluded_region.rpts
 +
      _explant.i2i  _day11.i2i  _day7.i2i _day7_noex.i2i _day11_noex.i2i _day7_noex_halfex.i2i _day11_noex_halfex.i2i
 +
  (if multiple zip files were analyzed, only the files from the last one will be left, since they get reused)
 +
-dont_recalc only for diagnostics. does NOT restrict the analysis to just the growth away from the wall.
 +
with this specified this entire program should just reproduce the numbers we already
 +
have in *Results.txt since that uses the entire area. ie, this make the program a no-op.

<nowiki>
 +
  mask_gedmat_images4_new.pl
 +
The easiest way to call this is via analyze_gedmat9.pl, see its help.
 +
 
 +
This version has the following changes compared with mask_gedmat_images3.pl:
 +
 +
1. @stats = &outline_stats(@outline) was used to calculate explant center (for masking) but
 +
        the meanx and meany are just the mean of the outline, it is NOT a center of mass. usually ok for a compact explant.
 +
  sub calc_com() is now used instead to calculate the true center of mass.
 +
-use_explant_outline will cause the OLD method to be used instead.
 +
 +
2.  bounding box was used to calculate area for sorting the outlines temporally (from smaller to larger area).
 +
      but when outlines intersect bounding box can at times NOT be a good surrogate for area.
 +
  $roi_area[$r] = ($maxx-$minx)*($maxy-$miny); 
 +
  handled these two issues by writing sub calc_com().
 +
-use_bbox_area will cause the OLD method to be used instead.
 +
 +
 +
note: fiji areas are already sorted smallest to largest when I first bring them in (extract_area2.pl does that):
 +
  $prev_results = `extract_area2.pl -justfiles=$resultsfile`
 +
  so I should do not need to use the sorted roi indices on them (so I've been doing this correctly). but the rpts are
 +
  being sorted based on bounding box, and fiji areas based on the true area in the Results.txt file. So the ordering
 +
  may be different at times. No change was made to this.
 +
 +
  mask_gedmat_images4.pl  -check_intersect  added.
 +
determines when outlines intersect and sets the aerr (area error flag) in the
 +
output file. eventually it will calculate areas a different way when that happens
 +
rather than combining masked images (see ~/krypton/Corvera/Raz/README for 10/18/13). right now only sets the error flag.
 +
 +
  Examines all the zip files (produced within fiji when outlining regions) in the current directory. These have
 +
  the boundary of the explant, day7 growth, and day11 growth.
 +
  note: this program assumes that all the data in the directory is from the same patient and the same tissue type.
 +
 
 +
  It recalculates the area measures by only including that part of the day7 and day11 growth which is between the explant
 +
  center and going towards the center of the well; area from the explant center going away from the center of the
 +
  well (ie, growing towards the well wall) is excluded. By doing this, we hope to minimize the
 +
  effect of growth (as measured by area) being stopped by the well wall when the explant is near the well wall. 
 +
  Output is written to stdout. The comments there explain the fields. area_mex is the old value, area_mex_border is the new.
 +
 +
  This is done by finding all the *_Area.zip files in the current directory, pulling out the outlines in those files
 +
  and using that information to recalculate areas.  It also needs to find the associated "combined" image file
 +
  (*_combined.i2i) to get image size and hence the position of the center of the well) and the fiji results file
 +
  (*_results.txt, so the numbers produced here can be easily compared with them).
 +
 +
  note: The algorithm assumes that the area NEVER DECREASES with time, and that the explant region is always surrounded
 +
by the day7 region which is surrounded by the day11 region. The latter assumption is sometimes invalid if
 +
the day 11 images were shifted relative to day 7 images; but that is usually ok.
 +
(if necessary, you can manually change the "bad_data" field in the output file to 1 and then use
 +
-cond in gedmat_to_xy.pl to eliminate those stats from further analysis.)
 +
It also assumes the smallest area in each zip file is the original explant area, the next largest area is
 +
called day7 area and the largest area (if 3 are present) is assumed to be day 11 area.
 +
Sometimes when growth is about 0, the outlines on, eg, day7, may have slightly less area than the original
 +
explant, so the outlines might be mis-ordered then. [actually it may read the correct day off the name of
 +
the i2i image now].
 +
 +
  note: If only 2 areas (ie, two .roi files) are present in the zip file, they are assumed to be for
 +
the explant and day7 (not day11).
 +
 +
  note: This program assumes the center of the combined image (usually 4 well images are combined into one) is the
 +
center of the well. see combine_images.pl. It also assumes the combined image name ends in combined.i2i
 +
(see -combined).
 +
 +
  note: some of the scripts I use to then analyze these results will multiply the area by 2, to get a "true" estimate
 +
  of growth; since the value produced by mask_gedmat_images3.pl will be (roughly) half of the real growth rates.
 +
 +
  usage:
 +
mask_gedmat_images3.pl  [options]
 +
 +
  options:
 +
-tmpdir=fullpathname directory to use for temporary files which are created, eg: -tmpdir=/home/lml/krypton
 +
 +
-zip_file=file.zip
 +
-zip_file=file.zip:file2.zip:...:filen.zip
 +
only examine the one specified zip file, not all those in the directory
 +
(If the second form is used, you can specify as many as you want.)
 +
note: you may still need to specify -zip_ending so that the ending of this file can be stripped
 +
      off correctly (so the -combined_ending and -results_ending can then be added correctly).
 +
-zip_ending=stuff e.g., -zipending=_area.zip  .  All files which end in this will be analyzed; default = _Area.zip
 +
-skip=file.zip[:file2.zip...]  list of zip files (without the full path) to skip.
 +
 +
-results_ending=stuff e.g., -results_ending=_results.txt  .  This is what the -zip_ending should be replaced by
 +
to get the name of the associated fiji results file.  note the _ should be included here
 +
if it was included in -zip_ending.
 +
 +
-combined_ending=stuff  e.g., -combined_ending=_combined_reduced_.i2i  . default = combined.i2i.
 +
This is any string which helps identify the last part of the combined image filename.
 +
-combined_scaling=#:# e.g., -combined_scaling=2:2 if reduceima -bin 2 2 was applied to get _combined_reduced_.i2i.
 +
 +
-scale=#:# distance and area (eg, -scale=2:4 if reduceima -bin 2 2 was used) scaling. This will multiply
 +
the area stored in the fiji file and the area calculated via my mask by the second number.
 +
The first number will multiply the distance of the explant from the center of the image.
 +
This option is just here to handle 001_BAP and 002_PRO datasets. They were analyzed in fiji
 +
with the images reduced by a factor of 2 in x and y. So the fiji areas produced will be low
 +
by 4x, as will my areas.  This option compensates for that.  See ~/Corvera/Raz/README for 10/11/13.
 +
 +
-check_intersect check if outlines intersect with the explant's outline. If so, set an error flag on stdout printout
 +
and print info to stderr.  eventually will just use area numbers rather than masking area in this situation.
 +
that is not done yet ...
 +
 +
 +
-save_day[=directory]
 +
saves the final binary mask for each days growth (eg, day7 growth minus the explant and minus the part growing towards the wall)
 +
into a 3d mask image (patientid_tissue_day#_mask.i2i).  This image will be reduced down in xdim and ydim from the
 +
original.  patientid_tissue_day#_.play_labels will also be created (labels which well each z slice comes from).
 +
This is mostly for quality control purposes.
 +
In addition, patientid_tissue_day#.rpts will be created (similarly reduced down in size) (coords may be off by 1?).
 +
View the file via: addlines maskim.i2i maskim.rpts -  |play.FC14 -P -1 R -labels maskim.play_labels -
 +
  or via: play_results3.pl
 +
patientid_tissue_day#_orig.i2i will be the original images (also reduced in xdim and ydim, and only one 2d slice
 +
from each original 3d image).
 +
note: older versions of play may need the comment line at the top of maskim.play_labels removed.
 +
note: if you want images to be in another directory, specify a full pathname, eg -save_day=/home/lml/krypton (without last /).
 +
note: any existing file with these names will be OVER-WRITTEN.
 +
note: this option creates lots of temporary files (in tmpdir) of the form __*.i2i, any existing
 +
      files that match this will be DELETED.
 +
see also: montage
 +
 +
-patient5 patient5 files have some odd naming. use this option if analyzing them.
 +
 +
-use_explant_outline legacy. specify this if you want the center of the explant to be based on the average of the pixel positions
 +
of just the pixels along the boundary (rather than the center of mass).
 +
-use_bbox_area legacy. specify this if you want to order the outlines based on their bounding box area rather than their true area.
 +
You should probably specify both options (if you want either one), I'm not sure about consistency if only one is specified.
 +
 +
-just_check just check whether each zip roi outline has the correct number of associated image files.
 +
eg, if the zip file has 3 outlines (explant, firstday, secondday) there should be two i2i files with DAY# in their name.
 +
prints to stderr info about those which don't have the correct number. does nothing else.
 +
-just_stats goes a bit further than -just_check (does that too), sets -verbose and prints out stats about each outline. then exits.
 +
-verbose some extra info to stdout
 +
-debug prints some tracing info to stderr
 +
-print_fname print name of each zip file as it is being analyzed, to stderr.
 +
-dlevel=# extra debugging. the bigger the number the more the printout. # is an integer starting at 1.
 +
-dlevel=1 will print a trace of commands to execute to mimic (parts of) this perl script.
 +
-noclean don't remove the temporary files which were created
 +
the files are: _ones.i2i _explant.rpts _day11.rpts _day7.rpts _excluded_region.rpts
 +
      _explant.i2i  _day11.i2i  _day7.i2i _day7_noex.i2i _day11_noex.i2i _day7_noex_halfex.i2i _day11_noex_halfex.i2i
 +
  (if multiple zip files were analyzed, only the files from the last one will be left, since they get reused)
 +
-dont_recalc only for diagnostics. does NOT restrict the analysis to just the growth away from the wall.
 +
with this specified this entire program should just reproduce the numbers we already
 +
have in *Results.txt since that uses the entire area. ie, this make the program a no-op.

===  membrane3D.pl  ===
 +
<nowiki>
 +
 +
A script to run the routines necessary to perform 3D membrane segmentation.
 +
note: it needs write permission in the directory where inputimage.i2i resides since all output images go there too.
 +
It will run the following programs, in order:
 +
  1. /home/lml/krypton/facil/i2i2mhd (convert to mhd format)
 +
  2. /home/lml/krypton/segmentation/MR-Source/ACME/ACME-Binary/bin/cellPreprocess (median filter, fill holes)
 +
  3. /home/lml/krypton/segmentation/MR-Source/ACME/ACME-Binary/bin/resample (resample pixel sizes)
 +
  4. /home/lml/krypton/segmentation/MR-Source/ACME/ACME-Binary/bin/multiscalePlateMeasureImageFilter  (determine the planarity of each region)
 +
  5. /home/lml/krypton/segmentation/MR-Source/ACME/ACME-Binary/bin/membraneVotingField3D (update planarity based on neighbors voting)
 +
  6. /home/lml/krypton/segmentation/MR-Source/ACME/ACME-Binary/bin/membraneSegmentation  (produce segmented regions via a watershed algorithm)
 +
Each program expects input files of a certain type (e.g. unsigned char).
 +
 +
 +
usage:
 +
  membrane3D.pl [options] inputimage.[i2i|mhd|mha] outimage.mhd
 +
 +
output files:
 +
  inputimage.mhd produced by i2i2mhd  - short ints
 +
  inputimage_med.mhd produced by cellPreprocess
 +
  inputimage_med_resamp.mhd produced by resample, unsigned char
 +
  inputimage_med_resamp_planar.mhd produced by multiscalePlateMeasureImageFilter, floating pt (doubles) between 0 and 1, how "planar" a pt is.
 +
  inputimage_med_resamp_eigen.mhd produced by multiscalePlateMeasureImageFilter, an eigenmatrix at each pt
 +
  inputimage_med_resamp_eigen_voting.mhd produced by membraneVotingField3D, result of voting, unsigned char
 +
  outimage.mhd produced by membraneSegmentation,  result of watershed, each region labeled with an id (short integer).
 +
 +
note: all units below are in the same units as the pixel units (I think). So if pixel spacing is 2 (um) in x, and a radius
 +
      of 2 is specified, that is a one pixel radius.
 +
 +
step 1. options for converting i2i to mhd:
 +
  -convert=dx:dy:dz  The first step is converting our i2i format to mhd format.  This specifies the pixel spacing
 +
in x y and z directions for that. default assumes 1:1:1. The "conversion" really just creates inputimage.mhd which
 +
is a text header which points to the original i2i image and gives some info about it. 
 +
If the input image has a .mhd or .mha extension already (instead of .i2i) then no conversion is done.
 +
Olga's images acquired with a 10x objective have a pixel size of .645 um/pixel (and z spacing of 10 um).
 +
Example: G03_x_1_1_binned.i2i has a pixel size of 2.5x2.5x10.  So -convert=2.5:2.5:10 specifies this in the mhd header.
 +
 +
step 2. options for cellPreproces:
 +
this may produce an unsigned char image (?)
 +
  -median=# radius of median filtering preprocessing (and hole filling). If this is not specified it isn't done.
 +
 +
step 3. options for resampling:
 +
this may produce an unsigned char image (?)
 +
  -resample=x:y:z  resample in the x y and z directions, eg. -resample=2:2:1 will halve the x and y dimensions and leave z unchanged.
 +
note: this will change the spacing between the pixels; but the routines which follow will understand that.
 +
For example: if after resampling, the pixels are spaced 10 um apart, then -planar=10 will use a sigma of 1 pixel.
 +
If this is not specified it isn't done.
 +
 +
  note: it may be necessary to do the above operations, which also convert the image into unsigned char, which is required for
 +
step 4, multiscalePlateMeasureImageFilter?
 +
  note: step 6 (watershed) may also work best if the pixel sizes are the same in all directions.
 +
 +
step 4. options relating to planarity:
 +
the planarity image produced will be doubles from 0-1.
 +
  -planar=# the sigma of the Gaussian used when classifying pixels as planar or not. default = 1
 +
  -alpha=# see the help for /home/lml/krypton/segmentation/MR-Source/ACME/ACME-Binary/bin/multiscalePlateMeasureImageFilter
 +
  -beta=# ditto
 +
  -gamma=# ditto
 +
  -c=# ditto
 +
  -planaropts="options for multiscalePlateMeasureImageFilter here" 
 +
available options (so far, but anything specified here will be passed), : -a # -b # -g # -c # -d -s -B -T
 +
options which go here should be specified in the format that multiscalePlateMeasureImageFilter wants them,
 +
for example: -planaropts="-c 5 -d -B"
 +
not in the alternative format that Membrane3D.pl desires (e.g. -planaropts="-a 5" is correct, -planaropts="-alpha=5" is wrong).
 +
    -stop_after_planar don't do anything after this step (e.g. voting for planar patches may not make sense if -B or -T specified)
 +
 +
step 5. options relating to voting:
 +
the resulting tensor vote image will be unsigned chars from 0-255.
 +
  -region=# the sigma which defines the region within which a pixel influences other pixels. default = 10
 +
 +
step 6. options relating to watershed segmentation:
 +
The resulting image will be long ints (id numbers) of regions. 
 +
                See the help for /home/lml/krypton/segmentation/MR-Source/ACME/ACME-Binary/bin/membraneSegmentation
 +
  -thresh=# threshold value. this is applied to the tensor voting image to turn it into a binary image. then a  distance
 +
transform and watershed are applied. default = 128
 +
  -segopts="options for membraneSegmentation here"   
 +
for example:  -segopts="-S -l 20 -a 5 -c -D" will use this exact string as options.
 +
options so far: -S -l # -a # -s # -n -i # -w # -m # -c -v -d -D
 +
 +
other options:
 +
  -verbose echo what is being done to stderr
 +
  -dummy don't really do anything; echo what would have been done to stderr.
 +
 
 +
example:
 +
reduceima -bin 4 4 G03_x_1_1.i2i G03_x_1_1_binned.i2i    - go from .645um/pixel, 10um in z -> 2.5um/pixel, 10um in z
 +
# -convert: just put correct pixel size info into an mhd header
 +
# -median:  smooth with a filter 10 um (4 pixels, since they are now 2.5um/pixel) in radius (diameter?)
 +
# -resample: change to a square pixel (10 um in x y and z). Change image format to unsigned char (needed by MultiscalePlateMeasureImageFilter)
 +
# -planaropts: options for planarity filter
 +
# -region:  width (in um) of neighbors for voting on planarity and updating it.
 +
# -segopts:

# /home/lml/krypton/bin/analyze_histo
 +
 +
Analyzes the output histogram image produced by histogram2 via the -f option.
 +
Prints out 2 columns: first column is bin number, second column is value at the cutoff.
 +
This is similar to the program "threshold" but instead of one threshold value for the
 +
entire image, it gives one at each distance (from a membrane).
 +
 +
Usage: analyze_histo [options] aimage_H.i2i
 +
options:
 +
-v: calculate cutoff based on percentage of voxels instead of percentage of light
 +
-f #: fractional cutoff (e.g., .80 = 80%), default = 0.950000
 +
-w #: number of bins for running average (default = 5), should be odd.
 +
-t #: only look at voxels >= intensity (must be >= 0), default = 1
 +
 +
Examples:
 +
histogram2 -f a_H.i2i -O a_H.histo -o -p 0 0 0 -d 40 -z 3 mask.i2i a.i2i b.i2i

===  analyze_yaodl  ===
 +
<nowiki>
 +
 +
This program reads in a yaodl file as produced by DAVE (volume widget menu: volume to surface ...)
 +
(hmc produces an ascii format which analyze_yaodl can't handle).
 +
It identifies connected surfaces (since DAVE considers all surfaces from one pass as one object).
 +
It then calculates and prints the volume and surface area of each connected surface.  Optionally
 +
it will write out a yaodl files (-y) for the largest surface found for each object, with better normals.
 +
This surface can be read back into DAVE with -y option.
 +
 +
Usage: analyze_yaodl [options] infile.ydl
 +
options:
 +
  -y largest.ydl:  write out largest surface of eac object to largest.ydl
 +
  -i image.i2i:  read in the image file associated with infile.ydl (not needed for anything yet).
 +
        -n: recalculate "better" normals (use this with the -y option)
 +
(dave used to produce terrible normals, now they are ok, so this isn't needed anymore)

===  BestPath3D  ===
 +
<nowiki>
 +
 +
Finds the brightest path from a start pixel to a stop pixel (1-indexed).
 +
Converts voxels into nodes in a graph and finds the lowest cost path from the start node to the stop node.
 +
The cost of each node is (maxval-imval), so bright nodes have less cost. Output in rpts format to stdout.
 +
BestPath3D always turns all (above threshold) voxels in the image into graph nodes. BestPath3D_ellipse only
 +
looks at voxels within an ellipse with a major axis connecting the start and endpts.
 +
Usage:
 +
BestPath3D [options] image.i2i > image.rpts
 +
BestPath3D_ellipse [options] image.i2i > image.rpts
 +
Options:
 +
-t #: threshold. Only pixels with values > # are allowed in the path, default = 0.000000
 +
-s x y z: start coordinate (1-indexed).
 +
-S x y z: stop coordinate (1-indexed).
 +
Up to 1000  pairs of start/stop pixels can be specified. At least one pair must be specified.
 +
-r scale black  rescale image values so new = (old-black)/scale prior to being used
 +
-n name name of object that is placed into the rpts file.
 +
-f exfac perpfac:  Only used if you are running BestPath3D_ellipse
 +
        sets principal axis a to have the specified endpts (from -s and -S), then expands it by factor exfac,
 +
                        and sets the length of the perpendicular b and c axes to be perpfac times the original axis a length
 +
defaults: exfac = 1.000000, perpfac = 1.000000
 +
-v: verbose

 +
BestPath3D_ellipse -v -t -1 -s 171 101 1 -S 170 99 30 -f 3 13 spiral_small.i2i > spiral.rpts
 +
note: spiral_small.i2i is a tough case, since the spiral goes very far from the start/stop points
 +
This requires a -f 3 to expand out the endpts and then a 13 to expand out perpendicularly.
 +
If you just expand out perpendicularly (e.g. -f 1 13) the ellipsoid doesn't grow faster enough
 +
near the endpts so some of the spiral data is not included in the ellipsoid. See -D option.

===  boundaryL  ===
 +
<nowiki>
 +
Usage:
 +
  boundary [options] original.i2i
 +
 +
Description:
 +
  Boundary takes an image, applys a threshold to the image,
 +
  rolls a ball outside then inside the object. This defines
 +
  what pixels are considered inside, outside, and boundary.
 +
 +
  Expects:  Input image and optionally some given options
 +
  Modifies: Nothing
 +
  Returns:  Output image with the name of image with _B added.
 +
            (if input.i2i was original image input_B.i2i
 +
            is output image)
 +
 +
Options:
 +
-I        : Do not roll ball inside of the cell.
 +
              (rolling the ball inside the cell results
 +
              in a smoother surface)
 +
-r #      : Set radius to # for sphere exterior to cell.
 +
              (default = 3)
 +
-R #      : Set radius to # for sphere interior to cell.
 +
              (default = 3)
 +
-t #      : Set threshold for all z slices to > #.
 +
              (default is 10)
 +
-T filename: Use file filename for thresholds for each z slice.
 +
              (one threshold for each zslice - one threshold on a line)
 +
-X        : Restrict search in X direction.
 +
              (can be used to cap a cylinder whose long axis
 +
              is along the x axis)
 +
-Y        : Restrict search in Y direction.
 +
              (can be used to cap a cylinder whose long axis
 +
              is along the y axis)
 +
-i string  : Add string to history of output image.
 +
-h        : Print this message.
 +
-H        : Print this message and then some.
 +
 +
Caveats:
 +
  Requires lots of memory and time to run (megabytes+minutes).
 +
 +
Notes:
 +
  Entire image name (with extension) is required.
 +
  Pixel values: boundary = 2, outside = 4, inside = 6.
 +
  Output image is padded on all sides by 2*radius+1 of
 +
  sphere rolled on the outside of the object.

===  calc_area  ===
 +
<nowiki>
 +
 +
This program takes in a surface image and a data image and calculates:
 +
1). the area of the surface (number of nonzero voxels)
 +
2). the number of data voxels (nonzero voxels in image2)
 +
3). the number of surface voxels (area) within a specified distance of a data voxel.
 +
This information is printed to stderr.
 +
 +
Typically one might apply a shrink_wrap to, say, a Vinculin image of a dual
 +
labelled image pair.  Then make_surface would convert this to a surface.
 +
After this, map_to_surface would be applied to the 2 dual labelled images.
 +
Then overlap would be used to calculate the overlap of the two data sets
 +
(given some overlap range, which defaults to 1).
 +
Then this program (calc_area) is used to get the area of the surface and the
 +
amount of it which is examined using the range specified to the overlap program.
 +
This is important since to calculate the probability that the overlap was
 +
due to chance you want to know what percentage of the area was included in
 +
the overlap calculation.
 +
 +
Usage: calc_area [options] surface.i2i data.i2i
 +
options:
 +
  -r range: range in voxels (default = 1).
 +
  -i image.i2i: also produce an output image
 +
  this image will have bit 2 set for original data voxels
 +
  and bit 1 set for surface voxels near (or on) data voxels
 +
  (so it would be a voxel with a value of 1 or 3).
 +
 +
note: entire image name (with extension) is NOT required.
 +
note: a - in place of an image name means stdin or stdout.
 +
note: a compressed image will be automatically be uncompressed.

===  closest_object  ===
 +
<nowiki>
 +
 +
Calculates the closest distance from an object in image1 to an object in image2.  Also calculates closest distance
 +
between objects within each image separately.  Prints out info about matches.  If no other object is within the
 +
maximum distance (see -m option), the object is printed matching to object -1 at a huge distance.
 +
Histogram of these distances is printed to stdout.
 +
The input images should have each pixel in an object having the object id as its value. These images can be
 +
produced with "countobjs -Q" or "objs_via_ascent" 
 +
 +
Usage:
 +
closest_object [options] image1.i2i image2.i2i > im1_im2.hist

 +
-m # :         maxdistance (in units used for -w) to look for the closest pixel, default = 10.000000
 +
-r #:         resolution for output histogram, ie, binsize, default = 0.100000

 +
-D image2d.i2i: the original intensity image for image2 (since image2 has pixel values as id numbers)

This programs reads in three images and produces a new version of image3.
 +
Each voxel which is colocalized (has image1 > thresh1
 +
and image2 > thresh2) has the value in image3 set to 32000 (-n 32000). Otherwise the value in image3 is not

changed.  Once these modifications are made, image1.i2i image2.i2i and newimage3.i2i can be read
 +
into DAVE (in that order) and voxels which are colocalized in the first two channels
 +
will be guaranteed to be colocalized in the third channel.

Phase 1: Associates each voxel in inimage.i2i which is > threshold with a maxima in the image.  It finds
 +
        the maxima by doing a steepest ascent walk in the image.  Writes summary info about regions found to
 +
        stdout in the same format as countobjs.  Only the location of the maxima found in phase 1 are passed to phase 2.
 +
        All vesicles must start out as maxima. (see also -readmax option)
 +
Phase 2: In each rolling window of time points (see -w), examines the intensity over time of each maxima
 +
        (found in previous step) to see if it
 +
        meets certain criteria (i.e., looks like a vesicle fusing with the plasma membrane - undergoing
 +
        exocytosis).  If it matches this criteria it prints out the "path" of the maxima and its
 +
        pixel value and iod value.  These paths can be converted to rpts format for
 +
        addlines or xmgr format
 +
        using found4.pl. 
 +
The fusion model: think of intensity as shown below. once the vesicle primes its intensity jumps. when it fuses
 +
it drops back down.
 +
 +
peak intensity profile:
 +
  pintens                  ----------------
 +
                          |                |
 +
                        |                  |
 +
                        |                    |
 +
  tintens -------------                      ------------------
 +
 +
          0  t1      t2                  t3
 +
          0  t1      |prise|              |ffall|
 +
 +
t1: time of tethering (should stop moving)
 +
t2: time of priming (peak intensity increases from tintens to pintens)
 +
t3: time of fusing (peak intensity drops back down, but iod should stay high and possibly even increase a bit)
 +
prise is the time it takes to rise froom tintens to pintens during priming (docking)
 +
ffall is the time it takes to fall from pintens to tintens during fusion.
 +
 +
exo4 is similar to exo3 but has slightly different options and checks all possible fusion times
 +
simultaneously. exo3 only picked the latest (in time) possible fusion event based only upon intensity
 +
changes during the falltime. exo4 considers what is happening elsewhen in the window before deciding
 +
on a fusion time. It picks the fusion candidate (iod rise and intensity fall) which is closest in time to
 +
the maxima disappearing (-check_max) and which has a stationary period (-primedtime) within the
 +
specified time range. Hopefully this makes it less likely to make mistakes.
 +
 +
Should work in 2d or 3d.  Only reads in a window of time points at once
 +
so should be able to handle large images.
 +
 +
Usage:
 +
  exo4 [options] inimage.i2i  > inimage.count
 +
 +
Options:
 +
 +
options related to input:
 +
  -T startt stopt : only examine these time points (0-indexed, inclusive)
 +
  -p numskip numuse : patterned read.  skip numskip z planes, then analyze numuse zplanes, then repeat.
 +
  This is useful if the acquisition protocol was, e.g., 1 fps for 1 min, 20 fps for 3 seconds
 +
  repeated over and over, and you only want to look at the 20 fps data.
 +
  numuse must be >= window size (see -w option). Pattern starts at t=0 even if -T is
 +
  specified (but startt time points are still skipped).
 +
  -w #         : number of time pts in a window, default = 100
 +
                        a negative number means read in entire dataset at once (one big window)
 +
  -jump # : jump # time pts before examining next window of time pts. This doesn't skip data, just
 +
  analyzes a "window" less often (so more has changed). Default = 0
 +
                        which means the very next time pt is added to window (and oldest dropped) and then
 +
                        the window of data is re-evaluated. May not work with -p option.
 +
  -r rptsfile : read in rptsfile.  should have one closed object in it. Uses this as a mask for all the planes.
 +
  -d tdim : the time dimension of the image (over-rides anything stored in the header)
 +
  -b #: : blur (smooth) image before looking for objects (maxima), using a window of the specified
 +
: halfwidth (in pixels) in x,y, and z (z width will be set to 0 if 2*width > zdim).
 +
 +
Phase 1: options related object finding via ascent (see objs_via_ascent2d), info printed out.
 +
          If an object doesn't satisfy these criteria, its maxima is not kept, so it is not considered a maxima
 +
          for the next stage of processing which tracks maxima into paths and checks if they are fusion events.
 +
          The iod and size specified here are also used later, but the next phase just looks with the square iod region.
 +
  -t threshold : any voxel > threshold in inimage.i2i is tracked to a 3d maxima (default = 0.0).
 +
  -i miniod maxiod : erase all objects whose iod doesn't fall in the specified range (default: 1-1000000000)
 +
  -s minsize maxsize : erase all objects whose size (in voxels, inclusive) doesn't fall in the specified range
 +
  (default = 1-1000000). note: object size and iod might be large since all voxels which
 +
  connect up via steepest ascent algorithm to the maximum count in this first phase.
 +
  -strict_max : ignore "maxima" which are really on a plateau (option might cause
 +
                        saturated maxima to be missed)
 +
  -readmax file : skip phase 1, instead just reading maxima in from the specified file
 +
 +
Phase 1b: noptions related to fitting Gaussians (not used for anything yet):
 +
  -g # : fit Gaussians (+ dc term) to each object found (eventually I will use this for something).
 +
  only includes pixels in object within # pixels from the brightest point.
 +
  -G # : same as -g, but uses gradient info of fuction during fit (i.e., a different fit routine).
 +
  The -G version seems a bit buggy.
 +
  -n : normalize the Gaussian fom (shouldn't affect individual fits, just allow comparison between fits
 +
 +
Phase 2: options related to "paths" over time:
 +
  Maxima must exist for 0 time pts, be stationary for 0 time pts prior to disappearing
 +
  While a maxima is present, a pixel within range only counts as part of object
 +
  if above threshold (-t option).  While a maxima is present,
 +
  a region will only be considered if size (pixels > thresh and within range) is within size (-s)
 +
  and iod is within iod (-i option).
 +
  -iodsize #           check iod within +/- range pixels., default = 3
 +
  -maxspeed #   max distance a maxima can move (in pixels) between time points, default = 5
 +
  -diststill #          how far (in x or y) in pixels a maxima can move and still be considered "still",
 +
  (this is the location compared to last position of maxima) default = 0
 +
  -fall time frac   maximum # of time pts peak intensity can take to show the specified fractional decrease
 +
  when vesicle is fusing. default = 10 and 0.300000
 +
  -iodrise frac   the fractional increase in iod which must be seen
 +
  when vesicle is fusing (see -fall). default = 0
 +
  -check_max #   vesicle must also change from max to not a max within # timepts after fusing
 +
  -minpeakval #          peak intensity value must exceed this when vesicle is fusing (-fall time  parameter)
 +
  -primedtime # #   minimum and max # of time pts vesicle must be primed before fusing.
 +
 +
options related to output:
 +
  -debugpath x y z      print out debug info about the path that passes near (within 5 pixels) here
 +
                        (fgrep output for the word: debugpath). can be used 10 times. 1-indexed.
 +
  A -1 for z, means debug any path near x and y, regardless of z value (only if -L used).
 +
  -neardebug #        for -debugpath, definition of near, in pixels, default = 5
 +
  -onlydebug      : only print out info for debug paths. ignore all other paths.
 +
  -a : print all info about each object found (like countobjs does) rather than just summary stats
 +
                      : for each time point.
 +
  -o outimage : create an ouput image of marked objects (object ids reused each time point). Max of each
 +
: object will be marked with the negative of the object id.
 +
  -fit_model : fit a square wave to intensity profile of each vesicle found to be fusing (and to debugpaths)
 +
                        not used for anything yet.
 +
  -v : verbose

===  exo6  ===
 +
<nowiki>
 +
This programs find vesicle fusion events in a 2D time series.
 +
 +
Each maxima (-readmax) gets a size and iod associated with it.  Only pixels > threshold (-t)
 +
within the iod region (-iodsize) count toward the iod and size.  Once the maximum disappears
 +
(-nomax_length) the region centered around the previous location of the maximum is used.
 +
Maxima are tracked from one time pt to the next by finding the closest maxima (within -maxspeed)
 +
to its previous location.  Tracks continue after the maximum disappears for -nomax_length time pts.
 +
 +
At the end of this time, the path is then analyzed to see if it meets criteria for a fusing vesicle.
 +
All time pts during which the maxima exists must have an iod within the correct range (-i) and
 +
and correct size (-s). The fusion time is identified by the intensity of the maxima falling
 +
fast enough and far enough (-fall); while within the same interval the iod rises enough (-iodrise).
 +
Fusion time is then further refined to be the time of largest iod increase (between adjacent time pts)
 +
within this interval.
 +
 +
A fusion event may also need to be the correct time interval from when the maxima disappears (-check_max).
 +
It may also need to be significantly brighter than the background (-minpeakratio).
 +
It may be required to have a minimum peak value during fusion (-minpeakval).
 +
 +
Once the fusion time is found, the program finds the stationary (-diststill) time interval prior to fusion.
 +
This (priming) time interval must be within certain constraints (-primedtime) for the path to be considered
 +
representing a valid fusion event.
 +

insufficient number of arguments
 +
This program pads an image in z, then calls "invariant" (with -F 10) to produce multiple resolutions
 +
of the original image along with its 2nd derivative in the gradient direction.
 +
The blurred originals are used to find the location of the maxima. The derivative images should
 +
have a zero crossing at the inflection points (eg, "edges"). The maxima should be in regions with
 +
negative second derivative. This program then calls flood2zero to find the spatial extent of each
 +
"blob" (bright region surrounding the maxima). Ideally this should just be a flood fill until
 +
the zero crossing is found, but noise, etc. means that a lower threshold works better.

<nowiki>
 +
 +
This program takes an image and scans it vertically in y at dx intervals.  It counts the number of
 +
times a vessel of at least the specified width is entered.  A vessel is any pixel with the specified
 +
intensity value.  Each z slice in analyzed separately (and read in sequentially).  A count of vessels vs time and dx displacement is
 +
written to stdout.
 +
See /home/lml/krypton/Corvera/grant2010.
 +
 +
Usage: find_vessels [options] image.i2i
 +
options:
 +
  -z start stop: zplanes to analyze. 0-indexed inclusive. default is all z planes
 +
  -i #: intensity of a pixel in the vessel. default = 32767
 +
  -w #: minimum vertical width of vessel in pixels, default = 2
 +
  -d #: dx step size, default = 100

===  flood2zero  ===
 +
<nowiki>
 +
 +
This program takes an original 3D image, a 2nd derivative image
 +
as produced by invariant -F 9 -b, and a list of 3d maxima and produces
 +
a new image which is just those voxels from orig.i2i that are negative
 +
(the 2nd derivative of a bright spot is < 0) in the derivative image
 +
and connected to a 3D maxima.  So it is used in conjuction with invariant
 +
to identifiy bright blobs (eg, synapses) in a 3D image.
 +
 +
Usage: flood2zero [options] orig.i2i deriv.i2i image.pts newimage.i2i
 +
options:
 +
  -b # : which resolution of maxima to use (object=noderiv_maxima# in pts file)
 +
  -v #  : instead of using 0 as the object boundary cutoff, use #
 +
        -z low hi: zrange to examine, zero-indexed, inclusive.
 +
  -d dist: max chessboard distance (in voxels) from each point to flood fill.
 +
  -s size: maximum size in voxels of an object (will truncate to this size), default= 10000
 +
  -o file: save object (blob) statistics to specified file. This is very similar to
 +
what countobjs would produce when applied to newimage.i2i except newimage.i2i
 +
can have blobs which touch (due to the size contraints here) and hence show
 +
up as one large blob instead of two smaller blobs. Also, if the header for the
 +
image has a scale factor in it (which invariant writes) this scale factor will
 +
be used to convert all statistics back into original unscaled values.
 +
 +
note: entire image name (with extension) is NOT required.
 +
note: a - in place of an image name means stdin or stdout.
 +
note: a compressed image will be automatically be uncompressed.

===  histogram2  ===
 +
<nowiki>
 +
Usage:
 +
  histogram2 [options] boundary.i2i aimage.i2i bimage.i2i
 +
Description:
 +
  This program creates a number of histograms of intensity or volume as a function of
 +
  distance of the object voxels from the nearest background voxel.
 +
  Requires:
 +
    boundary.i2i - boundary image created with boundary or createBoundary.
 +
object voxels are those with a value of 6
 +
background voxels are those with a value of 4
 +
border voxels are those with a value of 2
 +
all other voxels are ignored.
 +
            NOTE: by default this is assumed to be padded by 7 pixels all around.
 +
                  ie, IT IS LARGER THAN aimage.i2i and bimage.i2i
 +
                  createBoundary does this. see -p if you don't want this default.
 +
    aimage.i2i  - data image a.
 +
    bimage.i2i  - data image b.
 +
  Returns:
 +
    aimage_H.histo - output file with histogram info (-H can change this).
 +
  Output file format (10 columns):
 +
  1. bin number (i.e., distance from background) (each bin = 0.1 pixels)
 +
      note:a pixel touching the boundary is a distance of .5 (center is .5 from edge)
 +
  2. histogram of intensities in image a.
 +
  3. number of pixels in this bin (i.e., volume at this distance).
 +
  4. histogram of intensities in image b.
 +
  5. histogram of intensities in image a > athreshold (intens-thresh if -s option used).
 +
  6. histogram of intensities in image b > bthreshold (intens-thresh if -s option used).
 +
  7. histogram of intensities in image a, where values in a are such that
 +
      if (image a > athreshold)  and (image b > bthreshold), a=a (a-athresh if -s option) else a=0.
 +
  8. histogram of intensities in image b, where values in b are such that
 +
      if (image a > athreshold)  and (image b > bthreshold), b=b (b-bthresh if -s option) else b=0.
 +
  9. # of pixels in image a > image a threshold (at this distance), like 3 but only
 +
      counting voxels > threshold.
 +
  10.# of pixels in image b > image b threshold (at this distance), like 3 but only
 +
      counting voxels > threshold.
 +
 +
Input Options:
 +
  -o    :  border pixels are background voxels (default is object voxel)
 +
  -p x y z  :padding in x,y,z included in the boundary image  (default 7 in all directions).
 +
          (boundary image found in the programs boundary and
 +
            createBoundary are by default padded by 7 pixels
 +
            on all sides of the image.
 +
 +
Distance Options:
 +
  -P x y z : don't find histogram of all pixels to boundary, just the distance
 +
            of this pixel from the boundary. Can be used multiple times on command line.
 +
            (x,y,z) is 1-indexed (like play) aimage.i2i coordinate values.
 +
  -d #:    maximum distance (in pixels) to check, default = .5*(min dim)
 +
          Any pixel further than the maximum distance is considered to be at the maximum distance.
 +
          This apply also for the -ta and -tb distance based thresholds.
 +
  -x #  :  set x weight to # (default 1.0).
 +
  -y #  :  set y weight to # (default 1.0).
 +
  -z #  :  set z weight to # (default 1.0).
 +
  -F    :  Fast histogram - voxel level (default fast).
 +
  -S    :  Sub-voxel resolution histogram(default fast).
 +
  -Y # #:  limit Y direction from # to # (default off).
 +
          If the long axis of the cell is in the in the y direction,
 +
          and the cell is cut off, using the -Y option will limit searching
 +
          for the boundary in that direction, i.e. the ends past these values will
 +
          not be considered part of the boundary.
 +
          (similarly true for -X and -Z options)
 +
  -X # #:  limit X direction from # to # (default off), inclusive, 1-indexed.
 +
  -Z # #:  limit Z direction from # to # (default off).
 +
  -c:    pixels outside the image are considered border pixels.  For example, if the outlines
 +
          used to create boundary.i2i were in z=1, but you want pixels inside the z=1 boundary
 +
          to be counted as being 1 pixel away from the boundary (eg, from the phantom z=0 slice)
 +
          use this option.
 +
 +
Threshold Options:
 +
  -a #  :  set aimage threshold to # (default 0.000000).
 +
  -b #  :  set bimage threshold to # (default 0.000000).
 +
  -s :    subtract thresholds (and then clamp to >=0) rather than simply keeping intensities > threshold.
 +
          This is more like what you might want to do to subtract off background or nonspecific flourescence.
 +
  -ta athresh.txt  :  apply different thresholds at different distances to aimage.i2i.
 +
                    athresh.txt as produced by analyze_histo (applied to -f aimage_H.i2i output)
 +
  (i.e., 2 columns: bin # (tenths of a pixel) and threshold).
 +
  -tb bthresh.txt  :  like -ta, but for bimage.i2i
 +
  -ra # :  rescale athresh.txt prior to use, multiply values in file by #.
 +
  -rb # :  rescale bthresh.txt prior to use, multiply values in file by #.
 +
 +
Ouput Options:
 +
  -f aimage_H.i2i xdim ydim:  print out a full histogram of aimage. This is a
 +
          2D image (eg, aimage_H.i2i) with the specified x and y dimensions.
 +
          The x direction is pixel intensity, and the y direction bin number (tenths of a pixel) and
 +
          the pixel value wll be set to the number of voxels at that distance and that intensity.
 +
          Specify -1 for xdim or ydim if you want that dimension calculated automatically
 +
          (xdim will be approx. max intensity in image and ydim about 10*max dist, see -d option).
 +
          Explicitly set the dimensions if you will want to add this image with others (since they must all
 +
          be the same dimensions), e.g., to average data from a set of control files.
 +
          note: -S option will cause the "number of voxels" to appear to change.
 +
          Use the analyze_histo program to produce a distance dependent threshold file from this (e.g. to read
 +
          back into histogram2 on another pass via the -ta or -tb option).  This image can be large (25MB).
 +
  -H file: Output filename for histogram (instead of aimage_H.histo).
 +
  -A aimage_thresh.i2i  :  write out aimage.i2i after threshold is applied (for visualization purposes)
 +
                          these are the pixel values used to produce column 5 of aimage_H.histo
 +
  -B bimage_thresh.i2i  :  write out bimage.i2i after threshold is applied (for visualization purposes)
 +
                          these are the pixel values used to produce column 6 of aimage_H.histo
 +
 +
Miscellaneous Options:
 +
  -D distimage.i2i  :  print the distance image (for debugging). Each voxel is 100 times its distance
 +
    from the membrane (a pixel neighboring the background has a distance of .5 pixels).
 +
                      This can also be used by mask_image to then mask desired pixels.
 +
  -h    :  print this message.
 +
 +
Notes:
 +
  All the images should be oriented in the same direction.
 +
  Entire image name (with extension) is required.
 +
  A - in place of an image name means stdin or stdout.

===  image2ptsL  ===
 +
<nowiki>
 +
 +
This program takes an image, and identifies boundary pixels of objects.
 +
Boundary pixels are foreground pixels which have at least one
 +
backgound pixel among their 8 neighbors.
 +
In addition, any foreground pixel which is on the edge of a 2D
 +
slice is also considered a boundary pixel.
 +
These boundary pixels are written out in "addlines" format.
 +
Each zslice is analyzed sequentially.
 +
Points are unordered, and they are all considered part of one object.
 +
Points in the pts file have their value set to -1
 +
 +
Usage: image2pts [options] image.i2i pointfile.pts
 +
options:
 +
  -t #: threshold, above which is foreground. Default = 0
 +
note: entire image name (with extension) is NOT required.
 +
note: a - in place of an image name means stdin or stdout.

===  invariant  ===
 +
<nowiki>
 +
 +
This program takes an image, blurs it with a Gaussian of
 +
specified standard deviation and then takes derivatives of the image
 +
It does all of this in the frequency domain.
 +
 +
outfile is the root name for derivative of blurred images (outfile_dres#.i2i, unless -M),  plain blurred
 +
images (-b option, outfile_bres#.i2i) and/or pts files (-m or -M options, outfile.pts).
 +
 +
Any function which is a ratio of sum of products of derivatives (eg, (LxxLy + LyzLx)/(LyLy+LzLz))
 +
can be calculated.  Edit file init_invariant.c in
 +
/usr/people/lml/invitro/unc/curvature and recompile on molmed if you want a function which
 +
is not listed here.
 +
 +
Usage: invariant [options] infile.i2i outfile
 +
options:
 +
  -F #:  function to calculate.  Default = 1. Available functions are:
 +
  -F 1: LxLx+LyLy+LzLz : 3D gradient squared
 +
  -F 2: .5(Lxx+Lyy+Lzz)/sqrt(LxLx+LyLy+LzLz) : normalized 3D Laplacian
 +
  -F 3: LxLx+LyLy : 2D gradient squared
 +
  -F 4: sqrt(LxLx+LyLy) : 2D gradient
 +
  -F 5: 2(LxxLyy-Lxy^2)/(Lxx^2 + Lyy^2 + 2Lxy^2): 2D light or dark blobs (p. 252 IPMI '91)
 +
  -F 6: 2(LxxLyy-Lxy^2), same a -F 5, no normalization (so noise isn't magnified).
 +
  -F 7: mean curvature of 3D isointensity surface normalized by gradient squared
 +
  -F 8: mean curvature of 3D isointensity surface, no normalization.
 +
  -F 9: 2nd der. in the grad. direction times gradient squared.
 +
  -F 10: 2nd der. in the grad. direction (should = 0 at locations of edges)(use -u option).
 +
  -F 11 XYZ    e.g., -F 11 021  take zero derivatives in X direction, 2 in Y, 1 in Z (Lyyz).
 +
by calling invariant multiple times with various XYZ and using the -g option you
 +
can create a bunch of derivative images which you can then read in and combine
 +
however you like (e.g., my curvature_eigenvectors program)
 +
  -N #: normalize image intensities prior to use to be between 0 and #
 +
this performs: newval = #*(val-minval)/(maxval-minval)
 +
  -u #: during division (-F 2,5,7,10) set divide by 0 to this integer, default=0.
 +
        note: this is the final output pixel value, after any scale factors (-r or -R).
 +
        a good value is -32768, the minimum possible output pixel value.
 +
  -s sigx sigy sigz:  standard deviation in spatial domain of Gaussian.
 +
  -S sigx sigy sigz:  standard deviation in frequency domain of Gaussian.
 +
default = 3.402823E+38  3.402823E+38  3.402823E+38
 +
  -l # res2 res3 ... :  # = number of different resolution levels to calculate.
 +
res2 ... res# are the relative sigmas for each resolution level after
 +
the first one. eg, -l 3 .9 .7  means that 3 blurred levels should
 +
be calculated and the sigma (in the freq domain) of the second
 +
level should be .9 of the first level (ie, more blurred), and the 3rd
 +
level should be .7 of the first level (as specified with -S).
 +
  -L # factor:  # = number of resolution levels. factor is the relative sigmas in
 +
the spatial domain for each level relative to the previous level.
 +
  -e epsilon:  cutoff for Gaussian intensity calculation.
 +
default = 0.040000
 +
  -r: apply scalefactor to output so min= -32766 or max= 32766. This is useful
 +
especially when all the values would otherwise be < 1.
 +
This also prints to stderr the min and max values before rescaling.
 +
  -R #: rescale output by multiplying all values by #.
 +
  -m: calculate coords of 3D maxima after blurring and taking derivatives.
 +
Creates an outfile.pts file.
 +
  -M: same as -m, but also prevents writing out blurred images.
 +
        -b:         calculate coords of 3D maxima after blurring (but before derivatives). This
 +
        can be used with the -m option.  Objects associated with this option will
 +
        be named "noderiv_maxima#", where # is the resolution number.
 +
        This is useful for passing to flood2zero to find the extent of the bright spots.
 +
Also writes out blurred images (outfile_bres#.i2i).
 +
  -B: same as -b, but prevents writing out the blurred images.
 +
  -n #: maxima must have an intensity > # (must use -m, -M, or -b with this)
 +
  -f #: max pixel must be > all neighbors by at least # to be a maxima. default = 0.000100
 +
  -g: output a floating point image (no rescaling done). This output can be used
 +
by my curvature_eigenvectors program. -u option still applies.
 +
 +
note: image dimensions which factor to 2, 3, or 5 go fastest with the FFT.
 +
note: the entire image name is NOT required.
 +
note: compressed images will be uncompressed.
 +
note: a - in place of an image name means stdin or stdout.

 +
 +
NAME
 +
    epr - Exhaustive Photon Replacement (EPR) restores contrast by removing
 +
    residual out-of-focus light and improves resolution while maintaining
 +
    numerical accuracy of 3-D images of specimens obtained with serial
 +
    optical sectioning from wide-field or confocal light microscopy.
 +
 +
SYNOPSIS
 +
    epr [options] before-image[.tif] after-image[.tif]
 +
 +
DESCRIPTION
 +
    epr performs regularized, iterative image restoration with a non-
 +
    negativity constraint.  The before-image is a three dimensional (3-D)
 +
    TIFF image composed of rectangular, regularly spaced, optical sections.
 +
    Large images are decomposed into smaller, overlapping (in x and y only)
 +
    image segments for restoration, and the restored segments are recomposed.
 +
    The after-image is the restored 3-D image. All options must appear
 +
    before the image file names, but the order of options is not important.
 +
 +
    epr has the following options:
 +
 +
    -h                Prints basic help on syntax and available options.
 +
 +
                              Required Parameters
 +
 +
    -psf file[.tif]  The 3-D point spread function image file. The psf must
 +
                      match the optical configuration used for the before-
 +
                      image.  The psf depth (number of z-planes) need only be
 +
                      less-than or equal-to twice that of the before-image.
 +
                      Extra z-planes are symmetrically discarded.
 +
 +
    -smoothness alpha The alpha value where alpha is typically 0 < alpha < RNL.
 +
    -sm alpha        RNL is the residuals noise limit as reported by prepdata
 +
                      (see also). Smaller values of a correspond to less
 +
                      smoothing.  (RNL)^2 is usually a good starting choice for
 +
                      alpha.
 +
 +
    -iterations n    Maximum number of iterations to perform.  Iterating may
 +
    -it n            terminate earlier if convergence is detected. (see
 +
                      -convergence)
 +
 +
                              Control Parameters
 +
 +
    -scaling n        where n is after image scaling factor. Used to prevent
 +
    -sc n            integer overflow when saving after image to file.
 +
                      Default=1.0
 +
 +
    -convergence n    Criteria for terminating iteration, where n is << 1.
 +
    -co n            0.00001 represents true convergence. 0.001 usually
 +
                      achieves 90-95% convergence in about half the number
 +
                      of iterations.  Values of n larger than 0.001 are not
 +
                      generally recommended. Default=0.001
 +
 +
    -axial n1 n2      The z-axis object extrapolation beyond the sectioned
 +
    -ax n1 n2        image data where n1 is before first plane and n2 is
 +
                      after last plane. n is in planes.  By default,
 +
                      extrapolation extends +-1/2 the z-axis extent of the point
 +
                      spread function image and should be sufficient. Smaller
 +
                      values of n1 or n2 have the effect of spatially
 +
                      constraining the restored object and should be applied
 +
                      carefully.
 +
 +
    -time n1          The timepoint where you want the restoration to occur (0 indexed)
 +
    -t n1
 +
 +
    -threads n        The number of threads FFTW should use. Default=1
 +
    -th n
 +
 +
    -transverse n    The x-axis and y-axis object extrapolation in pixels.
 +
    -tr n            The epr process extrapolates the restoration beyond the
 +
                      bounds of each image segment in order to account for
 +
                      exterior out-of-focus contributions. Default = 1/4 of X or Y
 +
                      dimsenion PSF width, which ever is larger.
 +

===  map_to_surface  ===
 +
<nowiki>
 +
error: 
 +
There should be 3 or 5 main arguments (exluding options).
 +
Arguments seen:
 +
This program takes a surface (which are those voxels which are nonzero)
 +
and one (or two) data images.  It then maps (moves) the data voxels (nonzero
 +
voxels) to the position of the nearest surface voxel.  When done, one (or two) new
 +
image is produced which has the data values at these new positions.
 +
In addition, some statistics about the mapping are printed to stderr.
 +
 +
NOTE:A surface can be generated by Simple_2D_wrap or shrink_wrap.  This "mesh"
 +
representation of the surface (which DAVE can display using the -i option)
 +
can be converted into a surface .i2i image for map_to_surface using
 +
/usr/people/jac/cell/bin/make_surface -I surface.i2i -c 1 mesh.i2i surface.rpts
 +
The resulting surface is made up of voxels.  Voxels which are just below the
 +
surface will be considered to be a distance of 1 voxel from the surface
 +
(the distance between the centers of the two voxels).
 +
 +
Usage:
 +
  map_to_surface [options] surface.i2i image.i2i out_image.i2i [image1.i2i out_image1.i2i]
 +
Options:
 +
 +
a second input image and output image can be specified on the command line.
 +
 +
-c: rather than mapping data values to the nearest surface voxel, map
 +
a count of the number of data values which mapped to the
 +
surface voxel. I.e., if 2 data voxels mapped to a surface voxel, a
 +
2 is stored there (rather than the max of the 2 data values-the default).
 +
-b: rather than mapping data values to the nearest surface voxel, or
 +
a count, just map a 1 (ie, binary) onto the surface where ever a data
 +
voxel maps (regardless of how many map there or their intensity).
 +
-m: surface.i2i is actually a mesh file, not an image file
 +
produced from a mesh file.  In this case, only map data
 +
values to surface vertices (since map_to_surface doesn't
 +
yet know how to convert mesh files to complete surfaces
 +
like make_surface).
 +
      -d #:  minimum distance (in voxels) which data must be from the surface and
 +
still be mapped onto it.  Data closer than this is ignored.
 +
By default all data is examined (ie, min_distance = 0)
 +
      -D #:  maximum distance (in voxels) which data can be from the surface and
 +
still be mapped onto it.  Data further than this is ignored.
 +
By default all data is examined (ie, max_distance = 1/2 the minimum
 +
image dimension, this should include all of the data).
 +
      -x:    exclude data voxels which are already on the surface (they will be zeroed).
 +
(note: setting the minimum distance > 0 will not achieve the same effect since
 +
that would still allow a data voxel on the surface to match to a surface
 +
voxel at a neighboring position).

===  min_cylinder  ===

<nowiki>
 +
MIN_CYLINDER program - Version 1.0
 +
 +
This program takes an initial cylindrical mesh surface
 +
and allows it to deform to minimize a function of
 +
surface curvature and stretch and image intensity
 +
 +
Usage: min_cylinder [options] insurface infile outsurface
 +
 +
OPTIONS CONTROLLING TERMINATION CRITERIA:
 +
[-n #] Maximum iterations
 +
[-c #] Minimum pixel changes per iteration
 +
 +
OPTIONS CONTROLLING SURFACE SHAPE:
 +
[-w # # # # # #] Weights for Su Sv Suu Suv Svv E
 +
default = 0.20, 0.20, 0.10, 0.20, 0.10, -0.10
 +
NOTE: for a 2D time series, the u
 +
direction is usually in the xy plane
 +
and v is the time direction.
 +
-b:  use bilinear interpolation along the u coordinate
 +
      direction to calculate the energy component due to
 +
      the data. This option only works in conjunction with
 +
      the -D option. This causes all data along the boundary
 +
      in each xy plane to contribute to the energy of the
 +
      surface, instead of just voxels at the locations of the
 +
      vertices of the surface.
 +
      NOTE: does not use weights specified by -W option yet.
 +
-a:  same as -b but the average energy along the boundary is
 +
      calculated instead of total, so long lines are not preferred.
 +
-p:  same as -a but the average energy along each boundary segment
 +
      is weighted by the percentage of total boundary length which
 +
that segment contributes. So long bad lines count more than
 +
short bad lines.
 +
-g:  weight the data along the boundary by the dot product with the
 +
unit length vector normal to the gradient. Thus boundary segments which
 +
are parallel to the data gradient direction will count less than
 +
they otherwise would. Use with -b, -a, or -p option.
 +
-z #: the cost of a zero length line (before applying w6)
 +
      default = 0, only valid with -a or -b option.
 +
-N: use "normal" curvature instead of parameterization
 +
dependent curvature calculation.  This option should produce
 +
a more correct curvature calculation, so the program does not
 +
get fooled into thinking that small objects have smaller
 +
curvature.
 +
 +
OPTIONS CONTROLLING ALLOWABLE SURFACE MOVEMENT:
 +
[-D]  Restrict movement to 2 dimensions (x & y)
 +
[-s]  Skip first and last planes of cylinder
 +
      (so they won't move at all).
 +
[-S filename] filename of z planes to skip (do not use with -s).
 +
[-f]  Fix first and last planes of cylinder to move only in x&y
 +
[-F filename] filename of z planes to fix to move only in x&y
 +
(do not use with the -f option).
 +
[-A]  when the -F or -S flag specified, normally if two adjacent
 +
      slices are specified in the rpts file then the surfaces on
 +
      either side of these become independent of the each other.
 +
      If -A is specified then they will still affect each other.
 +
 +
OPTIONS CONTROLLING INPUT, OUTPUT, AND DEBUGGING INFO:
 +
[-W # # #] Weights for scaling x y z dimensions.
 +
[-r rescale]  rescale image data from 0 to rescale
 +
before using. default = 1000.000000
 +
    If rescale <0 then no rescaling will be done.
 +
[-u]  expect input image to be i2i - output also i2i.
 +
[-I #] write out vertex coords every # images
 +
      written in unc image format. can be read
 +
      in and displayed by wire. If SAVE_ENERGY is
 +
  defined then energy of each vertex also saved.
 +
      Currently SAVE_ENERGY is defined.
 +
[-i]  Copy information fields flag
 +
[-t "title"]  New image title
 +
[-d #]  Debugging level, 1 (least) to 2 (most)

===  morph3d  ===
 +
<nowiki>
 +
 +
This program does morphological processing on greyscale images. Currently the
 +
default intensity it filters with is a constant, although different shapes and
 +
intensity profiles are allowed.  Think of a 2d image as a 3d binary array of voxels
 +
where the height dimension is the intensity of the image at this x,y position.
 +
All those pixels which are less than or equal to the height are 1, others are zero.
 +
This object (made up of voxels which are 1) is the UMBRA of the image.
 +
 +
Dilation: Take the umbra of
 +
the image and the umbra of the filter. Then the image dilated by the filter is
 +
those voxels which get "reached" by the filter voxels when the filter umbra
 +
is translated through the image umbra (i.e., move the origin of the filter umbra
 +
everywhere inside the image umbra, all those voxels ever reached by the filter are
 +
part of the dilated umbra).
 +
For a constant intensity filter this reduces to just taking the
 +
maximum of the image intensities at the filter's locations.
 +
 +
Erosion: similar to dilation, but now as you move the filter around, only keep
 +
those voxels which, when the filter umbra is centered on them, permit all the
 +
filter voxels to lie on top of image voxels (i.e., the filter umbra fits inside
 +
the image umbra when centered on that voxel).Erosion is dilation of the background.
 +
This reduces to a minimum for a constant intensity filter.
 +
 +
Opening: erosion followed by dilation, can be visualized by taking the filter umbra
 +
surface and pushing it hard up under the image umbra surface. The highest voxels
 +
reached by the filter surface represent the new filtered image surface.
 +
(e.g. the "solvent or probe accessible surface" from below.
 +
 +
Closing: dilation followed by erosion.  Dilation can be visualized as
 +
flipping the filter umbra and rolling it along the top (outside) of
 +
the image umbra and recording the lowest voxels reached. (e.g.,the solvent
 +
accessible surface from above.).
 +
 +
If a 3D image is input, and a 3D filter shape is specified, then all analysis
 +
is done using 3D morphological filtering.  If a 2D filter is specified, then each
 +
zplane is analyzed separately.
 +
 +
Usage: morph3d [options] inimage.i2i outimage.i2i
 +
options:
 +
  -v: verbose, prints out which z slice is being analyzed to stderr.
 +
  -b #: any pixels <= # are background, ignore them. default = -32766
 +
  -h #: the maximum height (intensity) of the filter center relative to other
 +
                      entries in the filter. The default =0, ie all entries in the
 +
                      filter are at the same height.  If a nonzero value is specified
 +
                      a linear falloff in height to zero at the edges of the filter is
 +
                      assumed.
 +
  -m: when -m is specified the filter's intensities must fit under the
 +
image intensities without any intensities going negative. If this
 +
not the case, then a zero value is put in that center pixel location.
 +
For example, if we specify a filter which is 100 brighter in the
 +
center than at the edge, and the filter is over a region that is 50
 +
brighter in the center, then (if -m is not specified) that pixel value
 +
might stay 50 (since the template can fit under the image intensity by
 +
lowering itself so its edges have negative values).  If -m
 +
is specified, the filter will not fit and the pixel will get set to 0.
 +
  -f #:  morphological filter shape. 6 = jack (ie, 3D cross, default)
 +
7= 3D asterisk, 4 = 2D plus
 +
1= 2D filled square, 8 = 3D cube, 2= 2D filled circle,
 +
3= 2D asterisk, 5= 2D cross.
 +
2D shapes are done one zslice at a time.
 +
  -l #: just use a single LINE, of specified orientation .
 +
1 = LL-UR, 2 = UL-LR, 3 = Left-Right, 4 = Up-Down.
 +
5 = In-Out in z, 6 = ULIn-LROut (a diagonal in 3D).
 +
  -s # # #:  size of x,y, and z "radius"  in pixels (4 4 2 default).
 +
  [-e|-d|-o|-c]:      erosion (min), dilation (max), opening (e then d), or
 +
closing (d then e). default is closing.
 +
 +
note: entire image name is NOT required.
 +
note: a - in place of an image name means stdin or stdout.
 +
note: the origin of the filter element is at its center.

===  multi_gauss_deriv  ===
 +
<nowiki>
 +
 +
This program takes an image, blurs it with a Gaussian of
 +
specified standard deviation and then takes derivatives of the image
 +
It does all of this in the frequency domain.  The FFT will be done in parallel
 +
unless the environment variable NPROCS is set to 1.
 +
FFT_MAXMEM variable defines the maximum memory the FFT will use.
 +
outfile is the root name for images and/or pts (-m or -M) files.
 +
 +
Usage: multi_gauss_deriv [options] infile.i2i outfile
 +
options:
 +
  -x order:  number of derivatives in the x direction.
 +
default = 0
 +
  -y order:  number of derivatives in the y direction.
 +
default = 0
 +
  -z order:  number of derivatives in the z direction.
 +
default = 0
 +
  -s sigx sigy sigz:  standard deviation in spatial domain of Gaussian.
 +
  -S sigx sigy sigz:  standard deviation in frequency domain of Gaussian.
 +
default = 3.402823E+38  3.402823E+38  3.402823E+38
 +
  -l # res2 res3 ... :  # = number of different resolution levels to calculate.
 +
res2 ... res# are the relative sigmas for each resolution level after
 +
the first one. eg, -l 3 .9 .7  means that 3 blurred levels should
 +
be calculated and the sigma (in the freq domain) of the second
 +
level should be .9 of the first level (ie, more blurred), and the 3rd
 +
level should be .7 of the first level (as specified with -S).
 +
  -L # factor:  # = number of resolution levels. factor is the relative sigmas in
 +
the spatial domain for each level relative to the previous level.
 +
  -e epsilon:  cutoff for Gaussian intensity calculation.
 +
default = 0.040000
 +
  -r: apply scalefactor to output so min= -32766 or max= 32766. This is useful
 +
especially when all the values would otherwise be < 1.
 +
This also prints to stderr the min and max values before rescaling.
 +
  -R #: rescale output by multiplying all values by #.
 +
  -m: calculate coords of 3D maxima after blurring.
 +
  -M: same as -m, but also prevents writing out blurred images.
 +
  -n #: maxima must have an intensity > # (must use -m or -M with this)
 +
  -f #: max pixel must be > all neighbors by at least # to be a maxima. default = 0.000100
 +
note: image dimensions which factor to 2, 3, or 5 go fastest with the FFT.
 +
note: the entire image name is NOT required.
 +
note: compressed images will be uncompressed.
 +
note: a - in place of an image name means stdin or stdout.

===  objs_via_ascent  ===
 +
<nowiki>
 +
 +
Associates each voxel in inimage.i2i which is > threshold with a 3d maxima in the image.  It finds
 +
the 3d maxima by doing a steepest ascent walk in the image.  Writes info about regions found to
 +
stdout in the same format as countobjs.  Writes an image with each pixel labeled with its region
 +
id to outimage.i2i.
 +
 +
Usage:
 +
  objs_via_ascent [options] inimage.i2i outimage.i2i > inimage.count
 +
 +
Options:
 +
  -t threshold:any voxel > threshold in inimage.i2i is tracked to a 3d maxima (default = 0.000000).
 +
  -i miniod maxiod : erase all objects whose iod doesn't fall in the specified range
 +
  -s minsize maxsize : erase all objects whose size (in voxels, inclusive) doesn't fall in the specified range

*******  /home/lml/krypton/bin/overlap3
 +
This program calculates the overlap (colocalization)
 +
of two images. It is very similar to the overlap
 +
program, but produces a whole set of numbers with
 +
colocalization for each of many OFFSET DIRECTIONS at which
 +
voxels are considered to be "in the same place"
 +
In other words, suppose
 +
two data voxels are not exactly at the same location in the 2
 +
images, but are offset by 1 voxel in a specific direction. This
 +
program would count that
 +
as an overlap for, say, distance dx = -1, dy = 0, dz = 1.
 +
Output is text written to stdout. The OFFSET displacement is the displacement for
 +
image2. so OFFSET (-1,2,0) means image2 should be translated -1 in x (to the left), +2 in
 +
y (up 2) and not at all in z to align it with image1, e.g.,  tranima -T -1 2 0 image2.i2i image2T.i2i.
 +
 +
Usage: overlap3 [options] image1.i2i image2.i2i [maskimage.i2i]
 +
options:
 +
-m maxdist: maximum translational distance that should
 +
be checked (default = 1)
 +
-x maxdist: maximum x translational distance that should
 +
be checked (default = 1)
 +
-y maxdist: maximum y translational distance that should
 +
be checked (default = 1)
 +
-z maxdist: maximum z translational distance that should
 +
be checked (default = 1)
 +
-s step  : step size for translations
 +
(default = 1)
 +
-t thresh1 thresh2: only voxels in image1 > thresh1
 +
and voxels in image2 > thresh2 are
 +
considered for the overlap calculation.
 +
default = 0 and 0.
 +
-l:            keep things less than or equal to the threshold in image1
 +
                (default is greater than the threshold)
 +
-L:            keep things less than or equal to the threshold in image2
 +
                (default is greater than the threshold)
 +
      -v threshold:  all values greater than this value
 +
                    are part of the mask (default 0)
 +
      -V maskvalue:  this value is part of the mask
 +
                    can be used up to 100 times
 +
 +
note: entire image name is NOT required.
 +
note: a - in place of an image name means stdin or stdout.

===  prune  ===
 +
<nowiki>
 +
 +
This program takes an input image and prunes "dangling" paths from
 +
the image.  The input image is assumed to have already been thinned
 +
to a 1 pixel-wide center line using thin3Ds.  The output image can be
 +
converted to a pts file via im2pts.  Which paths get pruned depends upon
 +
the options specified.  By default, every end point is found and the
 +
path from the endpoint to first intersection point is deleted.
 +
The idea behind this program is to get rid of extraneous parts of the
 +
path produced by thin3Ds, to aid visualization.
 +
 +
Usage: prune [options] image1.i2i image2.i2i
 +
options:
 +
  -l #: only delete paths which are shorter than # pixels in length.
 +
  -s x y z:  x,y,z coords of a single path to keep.
 +
  -S x y z:  x,y,z coords of other end of the path to keep.
 +
(this should be used with -s).
 +
  -d datafile:  a file with lists of end points (start and stop) of
 +
paths to keep. Each line has a start and stop pt: (x1,y1,z1) (x2,y2,z2)
 +
  -X lx hix:    keep all paths whose endpts are within this x range (inclusive)
 +
If you specify any of X,Y,or Z, you must specify all 3.
 +
  -Y ly hiy:    keep all paths whose endpts are within this y range
 +
  -Z lz hiz:    keep all paths whose endpts are within this z range
 +
these 3 options are ANDed together.
 +
 +
note: all coords are zero indexed (ie, first pixel is numbered 0, not 1)
 +
note: entire image name (with extension) is NOT required.
 +
note: a - in place of an image name means stdin or stdout.
 +
note: a compressed image will be automatically be uncompressed.

 +
 +
Options:
 +
 +
-B  use sphere as initial surface (default cylinder)

 +
so input_image is not used for anything except
 +
for image dimensions. see OUTPUT below.
 +
-S Value for scaling blurred image
 +
    By default equals 1.0

 +
    NOTE: These points will NOT change in the shrink wrap
 +
    NOTE: They will not be dilated or moved in min_cylinder
 +
-v: verbose
 +
-I #: save vertex files and (if SAVE_ENERGY defined in min_cylinder)
 +
    files of the energy of the vertices every # iterations.
 +
      These can be read in and displayed by ~jac/bin/wire
 +
 
 +
ACTIONS:
 +
shrink_wrap takes a mesh of points and fits it to some
 +
surface.  To initialize the mesh, use planimeter to outline
 +
the cell in a few key z slices, include at least the first and
 +
last z slices, as well as any key features (bulges, bends, etc).
 +
To create an attractant function, a default Gaussian psf is used.
 +
This psf is located at /storage/big1/lml/Linux/bin/psf8.i2i.
 +
If this is compressed, make a copy in your favorite dir, uncompress
 +
and tell shrink_wrap where it is whith the -P option.
 +
 
 +
NOTES:
 +
Input:  this shell script expects the length of the cell to be
 +
        in the Y direction.  An rpts file should be created from a copy
 +
        of the image created with transp -YZ file.i2i file_T.i2i.
 +
        (where file.i2i is your image file, and file_T.i2i is your
 +
        image file transposed in Y and Z).
 +
Output: three intermediate files will be created (and deleted), one called output_root.i2i
 +
        which contains the coordinates of the final deformed mesh,
 +
        output.rpts which will contain an rpts file with a surface
 +
        drawn from output.i2i, and output__root_B.i2i which is the blurred input image
 +
source code is in /storage/big1/lml/jac/was_invitro/Projects/shrink_wrap
 +
 
 +
EXAMPLE:
 +
    suppose you have a cell cell.i2i that has its length in the Y direction.
 +
    and you want to save the cell output as cell_YZ_shrink.rpts:
 +
transp -YZ cell.i2i cell_YZ.i2i
 +
planimeter3 -I cell_YZ.i2i -R cell_YZ.rpts
 +
shrink_wrap -R cell_YZ.rpts cell cell_YZ_shrink >& cell.log
 +
  cell_YZ_shrink.rpts will be created (along with intermediate files cell_YZ_shrink* which get deleted).
 +
  The messages which result will be located in cell.log
 +
dave -I cell.i2i -T 1 YZ cell_YZ.rpts cell_YZ_shrink.rpts
 +
  (due to a bug you may have to zoom out of the image a bit for the rpts data to show up on dave)
 +
addlines cell_YZ.i2i cell_YZ_shrink.rpts - | play -P -1 R -

===  snakeTrack  ===
 +
<nowiki>
 +
 +
Tracking a 2D time series using snakes.
 +
The program takes as input an image (a 2D timeseries)
 +
and a starting contour for the first slice of the image
 +
in .rpts or .con format.
 +
The program will attempt to track the moving contour
 +
from one slice to the next.
 +
 +
It does this by mimimizing
 +
F = I - E where I is the internal energy of the snake and
 +
E is the external energy as represented by the input image
 +
The internal energy is defined as the similarity to the original
 +
shape of the starting contour.  If a con file is specified as
 +
input (instead of rpts file) it is recognized as such automatically
 +
by the magic number at its top (see ~dal/synapse/projects/snakeTrack for an example).
 +
Con files are 5-tuples: x y alpha beta lambda where alpha and
 +
beta are shape descriptors (which can be generated automatically
 +
by rpts2con).  Lambda is a weight on the local internal energy of deformation
 +
and 1-lambda is the weight on the local external energy.
 +
 +
The program will produce as output a
 +
.rpts file, which will contain an object for each slice.
 +
The objects can then be superimposed on the original image
 +
using addlines.
 +
A contour in .rpts format can be converted into the native
 +
GSNAKE .con format using rpts2con.
 +
For more information on snakes refer to
 +
http://www.cs.wisc.edu/computer-vision/projects/gsnake.html
 +
 +
Usage    :snakeTrack <image> <input rpts|con> <output rpts> [option]
 +
[ option ]
 +
-V          :verbose - show the multiresolution pyramid.
 +
-L#          :Number of levels of resolution, default 2
 +
-S#          :Stratified search segment spacing, default 2
 +
-N#          :The size of the neighbourhood around
 +
              a snaxel to be searched, default 2
 +
-D#          :Desired spacing between snaxels.
 +
              Default 5.  The program will try to keep
 +
              the spacing constant by inserting new snaxels.
 +
              It doesn't seem to do a good job deleting extra snaxels.
 +
-E/i/e/m    :External energy input type, default e
 +
              i - Use intensity as external energy value
 +
              e - Use edge magnitude and direction calculated
 +
                  automatically from the input image.
 +
              m - Use edge magnitude only, calculated automatically
 +
-slice # # :specify 0-based index of the first and
 +
              the last slice of the sequence
 +
 +
Note: options (L, S, N, D) must not have a space before arg.

 +
===  thin3Ds  ===
 +
<nowiki>
 +
 +
This program is for thinning (i.e., finding the skeleton or medial axis)  3D
 +
objects.  It is modified from Lee, Kashyap, and Chu (a parallel algorithm).
 +
The program attempts to thin the object, leaving only "center" voxels.
 +
It peels off outer layers until just the "medial" axis is left.
 +
Then the program converts the thinned image into a set of vectors in rpts format.
 +
The motivation behind this program is for creating thin lines (vectors)
 +
from an image data set.  These lines stay thin even when zoomed way up in DAVE.
 +
 +
This program is similar to thin3Dp but uses a sequential implementation rather
 +
than the parallel implementation of thin3Dp.  This version has no known bugs.
 +
Diagnostics (logfile info) are printed to stderr.
 +
 +
Usage: thin3Ds [options] image.i2i vectors.pts
 +
  -t #:  pixels above this are foreground (default = 0)
 +
  -n name: name of vectors put into vectors.pts.  The default = pixel_vectors
 +
DAVE requires objects in each pts file to have a different name.
 +
  -r: only keep rings.  all side_spurs should be removed.
 +
  -X low hi: only examine the image from low to hi in x (0 indexed)
 +
  -Y low hi: only examine the image from low to hi in y (0 indexed)
 +
  -Z low hi: only examine the image from low to hi in z (0 indexed)
 +
  -i filename:  create an i2i image of the center voxels.
 +
use this if you want to do further pruning (via "prune" command)
 +
 +
options for debugging:
 +
  -s rootname freq: save intermediate images to the specified file (rootname).
 +
    save them with a frequency of freq (1=save every, 2= every other, etc.
 +
  -p pass: save all the subpasses of this pass.filnames will be:
 +
"pass#_subpass#.i2i" unless -s is also specified in which case
 +
they will be "rootname#_subpass#.i2i"
 +
note: if you also want the -s option, you must specify it AFTER
 +
      this option on the command line.
 +
 +
example:
 +
    thin3Ds -i data_center.i2i data.i2i data_thinned.pts
 +
    prune data_center.i2i data_pruned.i2i
 +
    im2pts -n data_pruned data_pruned.i2i data_pruned.pts
 +
    DAVE -n 0 -I data.i2i data_pruned.pts
 +
 +
note: The only program which will correctly read in the pts file produced is DAVE.
 +
        This is because many vertices in the file should not be connected to their
 +
        previous vertex, and only DAVE correctly recognizes this.
 +
You MUST use the -n 0 option with DAVE when reading in the pts file produced.

A maxima still has to be above the threshold (-t) in intensity, and must be at least

"delta" greater in intensity than its neighbors (e.g, .5).  The halfwidth of the
 +
neighborhood is "hwidth" (ie, 1 means +/- 1 pixel).  A pixel is also not allowed to

be a maxima if more than "numbkgnd" neighboring pixels are background pixels (ie, <= threshold).
 +
If "ptsfile" is not "none" a pts file of the specified name will be written of the maxima.

zdim should be >> hwidth if it isn't = 1 (i.e., if it isn't a 2D time series).

<nowiki>
 +
 +
This programs takes a list of initial pts in a 3D image and tracks
 +
them over time.  It writes out the new list.  The image.i2i file should
 +
be a 3D time series.  The format for input.coords is coordinate triplets, one
 +
triplet per line, e.g.:
 +
x1 y1 z1
 +
x2 y2 z2
 +
Output is in a similar format but each point has all its time points printed
 +
in order, along with the pixel value at each location and the average of the 3 by 3 by 3
 +
neighborhood around the point.  Points are separated
 +
by a comment line (# at the beginning of the line)
 +
Tracking is performed by finding the brightest point in the neighborhood of the point's
 +
previous location in the time series.
 +
By default, pixel locations are assumed zero-indexed (first pixel is 0,0,0).
 +
The maximum # of pts allowed is 1000, the time series must be less than 400 in length.
 +
 +
Usage: track_pts [options] image.i2i input.coords output.coords
 +
options:
 +
  -x width:  change the default neighborhood halfwidth to search in x (default = 3)
 +
  -y width:  same for y
 +
  -z width:  same for z
 +
  -o: pixel coords in input.pts are one-indexed (like "play").
 +
coords in output.pts should also be one-indexed.
 +
  -m: Use this when the initial coords in input.pts are not exact.
 +
The program will move them to be the location of the brightest nearby voxel.
 +
  -c: perform hill climbing.  Instead of just going to the brightest point
 +
in the neighborhood, go to the brightest point in the neighborhood
 +
which can be gotten to by CONTINUOUSLY going uphill.  Without the -c
 +
small intensity dips (eg, between mitochondria) could be skipped over.
 +
  -i: do not allow a tracked point to move outside the neighborhood of
 +
it's INITIAL position (the default is the neighborhood of it's position
 +
in the previous time frame). note: the -m option is applied
 +
prior to this option (ie, results of -m define the "initial" position).
 +
-b x y z: also include, as the last "point" printed out, the average background
 +
around the point (x,y,z).  The halfwidth of the region can be set with -X,Y,or Z
 +
The coords are 0 indexed unless the -o option is also on the command line.
 +
-X hwidth: change the default halfwidth of the background region around (x,y,z)
 +
default = 5
 +
-Y hwidth: same for y.
 +
-Z hwidth: same for z.
 +
-v: verbose. prints extra info to stderr.
 +
-t tdim: don't read tdim from image header, just use this value.
 +
 +
note: entire image name (with extension) is NOT required.
 +
note: a - in place of an image name means stdin or stdout.
 +
note: a compressed image will be automatically be uncompressed.
 +
 +
see also: coords2pts.awk and coords2xmgr.awk to convert the output.coords into
 +
          either pts format (for addlines or DAVE) or xy format for xmgr.

-numthresh=#1:#2:#3  ignore the third number in the -t1, -t2, and -t3 options (or in the default) and instead calculate a

  #2 thresholds are applied to im2.i2i (ctx image), #3 thresholds are applied to im3.i2i (rin image).

  e.g., -numthresh=5:10:10 will apply 5 different thresholds to im1.i2i, and 10 thresholds to im2.i2i and im3.i2i.

  Using this option lets me insure that each call to coloc.pl will produce exactly the same number of data points;

# is the max n value (ie, all n values are scaled so the max over n1,n2,n3,n4 is #).
 +
Since p1,p2,p3,p4 are percent, # is typically set to a small part of that, e.g. .05.
 +
If # is negative then abs(#) is just used as a scale factor (so -1 would just keep the

===  compare2dist  ===

<nowiki>
 +
 +
This program calculates whether two amplitude distributions are the same.
 +
It was written to examine Rhonghua's STOCS data to determine whether the increase
 +
in observed STOC frequency could be explained by an increase in STOC amplitude
 +
(since then more events above threshold would be observed). 
 +
datafile2 should be the one with larger amplitudes (so we hypothesize it has fewer missing
 +
events if it is just a version of datafile1 shifted higher).  It will get shifted down
 +
by a range of shifts (-s option) and compared with datafile1.
 +
This routine also compares the temporal interarrival time distribution of each datafile with
 +
that predicted by a poisson process and with the other datafile; the temporal calculations
 +
ignore all missing data issues and shifting issues for now.
 +
 +
This program reads data in the form:
 +
    time calcium prior_baseline post_baseline amplitude
 +
      where the values are
 +
      time:            time of STOC
 +
      calcium:        SR calcium level
 +
      prior_baseline:  amplitude just prior to STOC
 +
      post_baseline:  amplitude just after STOC
 +
      amplitude:      amplitude amplitude of STOC (not relative to baseline)
 +
Data is expected to already be sorted by time (smallest to largest).
 +
comment lines must begin with a #
 +
 +
Usage: compare2dist [options] datafile1 datafile2
 +
options:
 +
    -t #: only include data with an amplitude > #. The default
 +
is to assume a 0 threshold. If you have acquired the data
 +
using some thresholding criterium (eg, only peaks above
 +
10picoamps are counted) then you should provide that number
 +
here, even if all your data is above this (ie, you've applied
 +
the threshold in your identification phase). This is because
 +
we need to know it when we shift amplitudes of the second
 +
distribution to see if it could match the first distribution.
 +
    -b: subtract average baseline from amplitude prior to use (ie, prior
 +
to any thresholding or intensity shifting of data).
 +
    -s delta max: shift datafile2 amplitudes down by a maximum of max, in
 +
increments of delta, to see if it will then match datafile1.
 +
  -p #: our guess of the percentage of data missing from datafile2 because it was
 +
below our threshold/detection criteria (a # from 0 to 1).
 +
This plus the amount of datafile2 shifted below threshold determines
 +
our estimate of the amount of data missing from the shifted datafile2 and
 +
the unshifted datafile1.  The larger this number is, the more likely
 +
the two curves will appear similar (since differences in actual data
 +
examined will be proportionally smaller differences, and we are assuming
 +
all missing data matches exactly, but see -m below). Default = 0.000000
 +
    -m: assume all missing data maximally MISmatches, this would probably be
 +
a worst case scenario, so that if the KS statistic says the distributions
 +
could be the same even with the -m option, its probably true.  But I'm
 +
not certain of this, since it really depends how this affects the
 +
relative spacing between the cumulative distributions. I'd have to
 +
think about it some more.

<nowiki>
 +
 +
This program calculates whether two distributions are the same using chi-square test (unless -k).
 +
It was written to examine the distribution of sizes of Ryanodine Receptor objects
 +
to determine if they are randomly distributed. datafile1 should be the reference
 +
data (gotten from many simulations or from a theoretical formula), datafile2
 +
should be the real data (max number of data values = 100000).
 +
 +
This program reads data which is just a list of sizes of objects seen (one per line).

Floating pt numbers are truncated to integers for bin number (max bin number = 50000).
 +

  -k perform K-S test instead (I'm not certain the numbins I use to calculate this is correct).

  -a also print the histograms produced
 +
  -b also print the normalized histograms (total count datafile2 scaled to the same count as in datafile1,

 +
so why is this option here?  if you just really want to use this program to do

image is the number of (image1,image2) voxels with that particular

The intent is to be able to look at the output image and get a sense

for whether there is a correlation between intensities
 +
in the two images.  If so, perhaps a least squares line

===  create_imagesL  ===
 +
<nowiki>
 +
 +
This program takes output from many runs of "overlap" and
 +
produces two images. One image is a percent colocalization image
 +
and the other is a probability image.  The overlap program MUST be
 +
run via the "many_overlaps" command.  The probability calculations
 +
are the same as those performed by "probcolocal", but only -n
 +
needs to be specified since the other values are automatically
 +
extracted from the file produced by "many_overlaps".
 +
 +
The percent image is the percent of voxels above threshold in image1
 +
(as originally specified to "many_overlaps") which overlap with
 +
voxels above threshold in image2. A 100 in the output image = 100 percent.
 +
The probability of observing as much (or more) overlap as we did due to
 +
random chance is the prob.i2i image.  Probabilities are mulitplied by 100.
 +
 +
Position along the y-axis (vertical axis) of the image, corresponds to
 +
thresholds for image2. The x-axis represents image1 thresholds.  The
 +
lowest threshold is the bottom left corner.  See the first line in
 +
your datafile for the range of thresholds this represents.
 +
Overlap produces statistics for a range of allowed overlaps.
 +
Create_images, by default, chooses an overlap within 1 voxel.
 +
If you want to use a different overlap distance use the -o option.

This program calculates the probability of an event occurring
 +
k or more times in n trials if the probability of an event is
 +
p and events are independent (see p.182 of Numerical Recipies)
 +
 +
It is intended as one way to determine if an observed level of
 +
volume colocalization is due to random chance or not. To use it
 +
in this manner, first find the fraction of voxels in each image
 +
which are used to calculate colocalization (e.g., those above
 +
threshold). Call these fractions f1 and f2.  Then, if these
 +
voxels were randomly placed, the probability that identical voxels
 +
are turned on in both images is f1*f2. An "event" is just such
 +
a coincidence, so p = f1*f2. n = number of voxels in one image.
 +
k= number of voxels which are observed to colocalize.
 +
This program then returns the probability that this amount of
 +
colocalization or more would have occurred merely due to chance.
 +
Note: if only an annulus (i.e., a subset of the total image volume)
 +
    is really being analyzed, then f1 and f2 and n should probably be
 +
    derived based on the volume subset, not the entire image.
 +
 +
Usage: probcolocal [options]

/home/lml/krypton/bin/roc
 +
This program reads two images. It attempts to use voxel values in
 +
image1 as a predictor of voxel values in image2; ie, as a type of
 +
measure of colocalization.  Both images are first rescaled to be
 +
between 0 and max (100).Then image2 is thresholded. Image1
 +
is then set,sequentially, to all integer thresholds between 0 and
 +
and max (unless -r is used to restrict the range).  If a voxel
 +
in image1 is above threshold then we guess
 +
that the same voxel is above threshold in image2.
 +
It also does the reverse, ie, use image2 to predict image1.
 +
The default cost function is:  1- 255*prob(detection)*(1-prob(false alarm)).
 +
 +
OUTPUT: 
 +
TO STDOUT:
 +
  The best thresholds, lowest cost and probability of detection,
 +
  prob of failure, prob of miss and prob of saying nothing when
 +
  there is nothing.
 +
TO A FILE:
 +
  6 images get created, they are the costs and probability of
 +
  detection and false alarm (3 separate images) when im1 is ussed
 +
  to predict im2, and another 3 for when im2 is used to predict im1.
 +
  By default these will be named:
 +
    im1predictingim2_c.i2i, im1predictingim2_pd.i2i, im1predictingim2_pf.i2i
 +
    im2predictingim1_c.i2i, im2predictingim1_pd.i2i, im2predictingim1_pf.i2i
 +
  The -p option changes the prefix (eg,the "im1predictingim2").
 +
  The images all have thresh1 on x axis, thresh2 on y axis.
 +
  The cost images are always scaled 0-255.
 +
  The pd and pf images are scaled 0-100.
 +
  Additional output files can be created with the -c option.
 +
SEE ALSO: playims . This program quickly puts up all 6 images
 +
  created by roc.  It can take arguments.
 +
 +
Usage: roc [options] image1 image2
 +
      options:
 +
-m max:    max of intensity range to rescale data to
 +
    the default is 0 to 100.
 +
-b val1 val2: ignore all background voxels. A voxel will be
 +
  ignored in both images if the voxel in image1
 +
  is <= val1 and the voxel in image2<= val2.
 +
-r low hi: range of intensity threshold values to check
 +
          in image1 (in original image intensity units),
 +
  default is entire intensity range.
 +
-R low hi: range of intensity threshold values to check
 +
          in image2 (in original image intensity units),
 +
  default is entire intensity range.
 +
-t thresh: only examine this threshold value for image1.
 +
-T thresh: only examine this threshold value for image2.
 +
  I am not sure -t and -T work completely correctly.
 +
-c file1 file2:
 +
  Creates 2 roc curve data files for graph and plot.
 +
    The probability of false alarm (x coord) and
 +
  detection (y coord) and cost (intensity) for all
 +
  thresholds in image1 for a threshold in image2
 +
  is written file1. A text string
 +
    indicating the image2 threshold level is written out.
 +
  This is then repeated for other image2 threshold levels.
 +
 +
  file2 is the same, but for image2 predicting im1.
 +
  Use: graph -f 1 -b <file1 |plot  to display these roc curves.
 +
-C d f m n: d is the "cost" of a correct detection, ie
 +
  a voxel in image1 is above threshold the same time
 +
  that the equivalent voxel is above thresh2 in
 +
  image2.
 +
  f is the cost of a false alarm (voxel in
 +
  image1 > thresh1 but voxel in image2 is < thresh2).
 +
  m is cost of a miss (im 1 <t1, im 2 > t2) and
 +
  n is cost of nothing present ( both im 1 and im 2
 +
  less than threshold, ie correctly predicting that
 +
  nothing is there).
 +
  Given these costs the program will print to stderr
 +
  the thresh1 and thresh2 values which minimize the
 +
  total cost. It will also print the total cost.
 +
  Total cost = d*pd + m*pm + f*pf + n*pn 
 +
  where pd = probability of detection, etc.
 +
  Typically, d = n = 0 and f = m = 1.
 +
-p pre1 pre2: prefixes for the names of the saved images
 +
  which show the sensitivity analysis. 6 images
 +
  get created (regardless of whether the p option
 +
  is specified), they are the costs and prob. of
 +
  detection and false alarm (3 separate images)
 +
  when im1 is used to predict im2, and another 3
 +
  for when im2 is used to predict im1.
 +
  By default these will be named:
 +
  im1predictingim2c.i2i, im1predictingim2pd.i2i,
 +
  im1predictingim2pf.i2i, im2predictingim1c.i2i, etc.
 +
  This option changes the prefix (ie, what comes
 +
  before the "c","pd",and "pf") for the
 +
  images saved. pre1 will be for im1 predicting im2,
 +
  and pre2 will be vis versa.
 +
-s file:  save roc data as an array of floats to "file".
 +
  Once this file is saved, any particular values
 +
  of costs can be examined very
 +
  quickly. In other words, this is the data that
 +
  the roc program is really taking a long time to
 +
  calculate. So if you want to examine the same
 +
  pair of images under different cost
 +
  scenarios, save the data file during the 1st
 +
  scenario, and run the others using the saved data.
 +
  NOT IMPLEMENTED YET.
 +
-f file:  read in a saved array (see -s above). When this
 +
  option is specified the args image1 and image2 are
 +
  not specified on the command line.
 +
  NOT IMPLEMENTED YET.
 +
note: entire image name is NOT required.
 +
note: a - in place of an image name means stdin.

sparkstats5 is similar to sparkstats3 (only examines the first 10 seconds of data from any cell
 +
and ignores cells which don't have 10 seconds of data).
 +
 +
It eliminates from any 2 second interval multiple events at the same site, since we guess that is
 +
due to a second "bursting" process which we want to ignore.
 +
All events in the same cell, at the same x,y are considered events from the same spark
 +
 +
Usage: sparkstats5 [options] datafile
 +
options:
 +
  -N #: spark events considered the same site if <= # pixels in x and y from first event and
 +
also in the same cell and 2 second interval (note: histogram produced does not compensate for
 +
the longer time some cells were under observation).
 +
  -O #: like -N. in addition, sparks with 0 events in a 2 second interval are added for
 +
each spark that exists in  an interval but does not exhibit spark events
 +
in some other interval in the same cell.
 +
  -i: spark events condidered the same "site" if in same cell and same 2 second interval
 +
this is the default.
 +
  -I: an extra spark id field does NOT precede the spark data (ie, test.data, not bestdata.data).

This program takes an object outputfile (unless -rptsin or -tripletsin) produced by countobjs (or maskobjs) and finds the minimal
 +
spanning tree connecting the center of mass of the objects, and the convex hull. Writes out connections as an rpts file to stdout.
 +
It also loops through 20 thresholds  for the pts, and prints to stderr some stats about the minimal spanning tree and
 +
convex hull of the points above each of these thresholds.
 +
 +
Options can be used to only selected a subset of the objects and to constrain the maximum distance (-maxdist).
 +
 +
It was written with the hope that triplets (maxima in an image which has a cell in the center) will show a pattern in their
 +
convex hull area, so that when the threshold rises high enough, only maxima inside the cell will still be present and hence
 +
the convex hull will be stable and of much smaller area.

This program takes 2 object outputfiles produced by countobjs (or maskobjs) and finds the shortest distance
 +
from the center of mass of objects in file1.out to the center of mass of objects in file2.out.
 +
 +
If both file arguments are the same (e.g., objs2dist.pl file1.out file1.out >file.dist), you can use this
 +
routine to find the distances between objects within an image (an object match with the same id is automatically
 +
ignored in this case so objects don't match to themselves). See also the option -skipsame.

See comments printed to stdout when the program runs to explain the fields in the output data.
 +
 +
Usage:

pt_distances [options] file1.rpts file2.rpts
 +
Options:
 +
-h: print histograms of distances. entry for pt at dist d:  histogram[int((d+tiny)/binsize)]++
 +
-t #: set tiny to #, default = 0.000010 . Points at exactly 1 pixel seem to be put into the .9 bin
 +
perhaps due to slight roundoff error. By adding tiny, they go into the next bin.
 +
      -b #: set binsize to # pixels, default = 0.100000
 +
      -m #: set maximum distance histogram will go out to (distances > this get put in last bin)
 +
default = 50.000000 pixels
 +
-a #: the area (in pixels) of the region used to generate file1.rpts and file2.rpts
 +
this is used to compare observed rates with theoretical rates if randomly distributed.
 +
NOTE: the theoretical calculations for image1 vs. image2 (and vice versa) are probably WRONG.
 +
default = 10000.000000
 +
-M #: the minimum distance allowed between maxima, for theoretical calculations. This might be
 +
1 (pixel) since maxima normally can't be next to each other. Or it might be the
 +
resolution of the microscope (since objects closer than that will appear as one maxima).

===  resolve_pts  ===
 +
<nowiki>
 +
 +
Takes minimimal spanning tree rpts file (just an rpts file with each pair of pts which are to be compared specified
 +
as a line segment, i.e., two pts and a "break") as produced by objs2mst.pl and finds which connected
 +
pts are resolved and which are not.  Resolved pts are those which have at least the specified
 +
intensity dip along the minimum cost (roughly: brightest) path connecting those pts. note: if there is no path between the two
 +
pts such that all voxels are greater than the threshold, the pts are also considered to be resolved.
 +
If a pair of pts is resolved, both are written to out.rpts (but not more than once).  If a pair of pts is not resolved
 +
then the brighter of the two (voxel intensity) is written to out.rpts.
 +
The intensity dip is the max amount the intensity goes below the dimmer of the two endpts (anywhere along the minimum cost path).
 +
Each pair of lines (i.e., pair of coordinates) in mst.rpts defines ends of a minimum cost path
 +
along which an intensity dip will be searched for. 
 +
 +
Usage: resolve_pts [options] image.i2i mst.rpts out.rpts
 +
options:
 +
  -t #: threshold, default = 0.000000
 +
  -f : normally a pt is discarded if it does not resolve against at least one other pt it is connected to in the input rpts file.
 +
Thus, AXXXXBXXXXC if A and B resolve, but B doesn't resolve against C, and B is smaller than C
 +
B will normally be discarded (even though it resolves against A, it fails against C).  If you specify -f
 +
then maxima which fail will be kept as long as they resolve against some other pt.
 +
  -d #: intensity dip required to be resolved. default = 10.000000
 +
  -p #: the percentage dip required relative to the dimmer endpt (e.g. 26 is 26 percent dip)
 +
  -l: instead of dip being the maximum amount below the dimmer of the two pts, dip
 +
is the max amount below a linearly interpolated intensity between the two endpoints.
 +
  -i: truncate coords written to out.rpts to integers (addlines prefers this I think).
 +
  -v: verbose.
 +
  -V: very verbose.

Examples:
 +
countobs image.i2i > image.objs

<nowiki>
 +
This program displays the four quadrant images of a well.  The user then saves 3 pairs of points
 +
(s when middle mouse is pressed). Each pair of points should be points that match in two
 +
neighboring quadrants.  When done, each quadrant must have one (or two) points specified.
 +
Points must be in pair order (see recalc_quadrant2.pl).  When done, the use must write them out
 +
via z (when middle mouse is also pressed, no confimation is given in play). 
 +
The quadrant images are then aligned based on these points and newimage.i2i is created.
 +
 +
It will also create a file with the output from play, for future reference.
 +
It will be named, eg, G02_combined_play.pts. It can be passed manually to recalc_quadrant2.pl to redo
 +
the alignment if necessary.

This program runs combine_images on all the images in the current directory.  All images which have names

like L##_morestuff.i2i (where L is any letter and # is any digit) will be combined;
 +
all the A02 will be combined (to produce A02_comb.i2i), all the A03, etc.
 +
The resulting image for the combination of the A02 images will be A02_tag.i2i (see -newtag option, e.g. A02_comb.i2i).
 +
Any images already existing in the current directory with a name like L##_stuff_oldtag.i2i will be ignored.

 +
usage:
 +

<nowiki>
 +
Parse a position file produced by Zeiss system to pull out x y coords for each of the images taken in well C09.
 +
Output triples (well_id x y) written to stdout.
 +
Position may be in microns, x increasing to the right, y increasing down.
 +
 +
parsepos.pl filename.pos
 +
 +
options:
 +
-well=string well to analyze. default = C09
 +
-pre=prestring add this string in front of the well_id
 +
-post=postring add this string after the well_id
 +
these two options are needed if you want to pass this output to
 +
overlap_image.pl -create=newimage.i2i, since that will need to be able
 +
to find the image associated with each well_id.
 +
-verbose additional output to stderr

Restores all the i2i files in the current directory. Skips any files with  _.i2i or _r.i2i in their name.
 +
Also ignores any files which do not have dat or ctx in their name.
 +
 +
options:
 +
-dummy just print what would be done
 +
-bkgnd=# pass this through to find_bkgnd as the -a option. eg, -bkgnd=-.10 will lower the bkgnd value
 +
which is subtracted off by 10 percent.

        -scale=#:#      GFP and RFP output scaling for restoration (respectively). default = 1.0 and 1.0.
 +
-verbose echo what is being done
 +
        -maxfiles=# only analyze this many files. primarily for debugging
 +
-twod during background subtraction, vary the background value for each 2D slice, instead of
 +
just using the same value for all z slices.
 +
-files=:file.i2i:...:filen.i2i  just restore these files. and do it even if _.i2i or _r.i2i exists.

===  recalc_quadrant2.pl  ===
 +
<nowiki>
 +
align_quadrants.pl calls this program.  It is easier to use it than to call recalc_quadrant2.pl manually.
 +
 +
This program converts from pts printed by play (so in the coordinate system gotten from combining the four quadrant images of a well (with no overlap))
 +
to one used by register_images.pl (ie, each pt is in the coordinate system of its own individual image).
 +
It also pairs the points up and orders them the way that register_images.pl requires.
 +
It assumes the user picked matching pairs of pts in order when using play.  Eg, first a pt was picked (s key while holding down middle mouse button),
 +
then its matching point in a neighboring quadrant was picked.  This was then repeated 3 times (so 3 pairs of points are present).
 +
note: the file names for the files associated with each quadrant are not stored in the output by default, just the quadrant number,
 +
      use -qnames to change this; they are needed if you want to subsequently have register_images.pl use chained.txt to actually combine the images.
 +
 +
 +
recalc_quadrant2.pl [options] < pts.txt > chained.txt
 +
 +
options:
 +
-res=# resolution the display was downsampled by prior to getting coords (ie, what was used in chres, see below).
 +
if chres was .5, then -res=2, ie, 1/chres value. default = 2.
 +
-xdim=# default = 1392
 +
-ydim=# default = 1040
 +
-qnames=name0:name1:name2:name3    file names associated with the images used to produce each of the 4 quadrants.
 +
  they must be in this order. If not specified, then the output will not be
 +
  usable by register_images.pl (unless -root is implemented there).
 +
-outimage=image.i2i also produce an output combined image (ie, call register_images.pl, see below).
 +
-qnames required for this option.
 +
-blend if -outimage is specified, then blend the overlapping images to produce the output image.
 +
-verbose print overlap info to stderr. maybe to use in -o option to combine_images.
 +
-debug stuff to stderr
 +
 +
more info. the quadrants in the combined image (see combine_images below) are numbered as follows:
 +
quadrant 1  |  quadrant 3
 +
quadrant 0  |  quadrant 2
 +
    where x increases to the right, y increases up
 +
 +
example:
 +
 +
# combine the 4 well images without overlap to see what pts might match between quadrants:
 +
    combine_images -o 0 F06_0_2_0_20140505_GEDMAT_P025_WES_OM_Day14.i2i F06_1_2_0_20140505_GEDMAT_P025_WES_OM_Day14.i2i

 +
 +
# look at the resulting image and identify matching pts:
 +
    chres -S .5 .5 1 tmp.i2i - |play -    # save (s) pairs of pts which match between the quadrants. print them using z.  create file F06_pts.txt:

===  blur3d  ===
 +
<nowiki>
 +
 +
Blurs an image by a psf.
 +
FFTs are done with 4 byte floats, so total space needed will be 4 times the padded image size (in voxels)
 +
plus the size of the two original images (image and psf)
 +
The input image can be real or short int format. The psf must be short int format.
 +
note: performs a convolution (not a correlation).
 +
note: fixed a small bug. 10/17/11
 +
 +
Usage: blur3d [options] image psf newimage
 +
options:
 +
  -S #:  scale (multiply) output values by # (to prevent underflow or overflow)
 +
  voxels which after scaling are > 32767 are set to 32767. voxels < -32766 are set to -32766.
 +
    -p # # #: pad the image in x, y, and z by the specified amounts
 +
by default image is padded (with 0) by 1/4 psf width all around,
 +
so its size for blurring becomes bigger by psf/2.
 +
psf is always padded to the same size the image becomes.
 +
Padding is stripped off before newimage is written, so it will be the same size as
 +
the original image.
 +
    -N # # #: pad so that the image has the specified dimensions after padding (just prior to FFT).
 +
  -n #: pad with # instead of boundary pixel values.
 +
  -Z:  pad with zero instead of the boundary pixel values.
 +
  -c # # #:  the center of the psf is at (#,#,#) zero indexed.
 +
                the default is to take the brightest pixel as its center.
 +
  -C:  don't center the psf at all (default is to center on the max, unless -c is specified).
 +
  -P:  normalize the psf so each slice (after padding) averages to 1. -P acts like an optical PSF.
 +
        the default is to normalize so the entire psf (after padding) has an average pixel value of 1
 +
              (the default keeps total light constant).
 +
  -d:  don't normalize at all.
 +
  -o:  do a cross correlation instead of a blur (convolution)
 +
  -R:  output image as 4 byte floating point instead of short integer.
 +
  -v:  verbose. print more info to stderr.
 +
 +
note: entire image name (with extension) is NOT required.
 +
note:  can read from stdin or write to stdout (use a dash instead of the file name)
 +
note: a compressed image will be automatically be uncompressed.

 +
===  canny  ===
 +
<nowiki>
 +
 +
This program reads in a 2 or 3d image and outputs the results
 +
of a 2D Canny edge detector on it. Canny is the derivative
 +
(in the gradient direction) of the magnitude of the first
 +
derivative (so it is a type of 2nd derivative). 
 +
NOTE: see option -n below for an exact answer.
 +
Each z slice is treated
 +
independently of the others.  Its application will often be
 +
preceded by a Gaussian blur and followed by the calculation
 +
of zero crossings.
 +
If an INT type image is input, an INT is output.
 +
If a REAL type image is input, a REAL is output.
 +
 +
Usage: canny [options] infile outfile
 +
  options:
 +
-d: Debugging flag
 +
-n: normalize the result. This option causes the true 2nd
 +
derivative to be calculated. Without it, only the sign
 +
of the second derivative is guaranteed to be correct
 +
(which is sufficient if only zero crossings will be
 +
calculated from it). Divides each point by Ix*Ix+Iy*Iy.
 +
-s #:  scale factor to multiply all output values by. This is
 +
useful if you are outputing an INTEGER image with a very
 +
small range of values which would otherwise all be truncated
 +
to just a few numbers.
 +
note: entire image name (with extension) is NOT required.
 +
note: a - in place of an image name means stdin or stdout.
 +
Example usage:
 +
To create a gradient edge strength image for a shrink wrap run:
 +
  blur_spatial image.i2i -|canny - -|zerosu - - |blur_spatial - out.i2i
 +

Usage: cblur [options] arg1.i2i arg2.i2i
 +
  For every zero valued point in each xz plane,  cblur
 +
  replaces the zero value with the -100 times the distance
 +
  from the nearest non-zero voxel in the xz plane.
 +
Options: None at this time.

===  center_of_mass  ===
 +

This program reads in a 4D image and translates each 3D image
 +
so its center of mass is moved to be the center of the image.
 +
One 3D image is read at a time.
 +
 +
Usage: center_of_mass [options] inimage.i2i outimage.i2i
 +
options:

 +
===  combine_images  ===
 +
<nowiki>
 +
This program reads a bunch of image files which have their xy position within a well stored in their header.
 +
It then combines the images. Karls acquisition program for the Zeiss microscope should automatically add
 +
this information to the header. A maximum of 50 images can be combined. Images must all be the same size.
 +
Images are also assumed to be aligned in z already. Images are added to the output image in the order specified
 +
on the command line, with later pixel values replacing previous values if there is an overlap of the images.
 +
 +
Usage: combine_images [options] im1.i2i im2.i2i [more input images]  outim.i2i
 +
options:
 +
-d debug. stuff to stderr.
 +
-f do NOT fill pixel locations which have no data with nearest data value (added 2/3/14)
 +
Filling is done by default to try to avoid introducing sharp intensity edges into the image.
 +
-X flip each input image in X before using it (-Y can also be specified at the same time)
 +
-Y flip each input image in Y before using it
 +
-p # over-ride the specified pixel size with this one (in um). The 2.5X objective has a
 +
pixel size of 2.58 um stored in the image header (for images acquired prior to 4/13/13)
 +
but it should be 2.41
 +
-x #:#[:#...]  rather than use the x positions stored in the image header use these x pixel positions.
 +
these should be the x offset of one image relative to another, in the same order as the
 +
image names on the command line (there MUST be one number for each image). For example:
 +
combine_images -x=0:500:0:500 im11.i2i im21.i2i im12.i2i im22.i2i outim.i2i  if im21.i2i and im22.i2i
 +
are displaced 500 pixels to the right of the other two images.
 +
-y #:#[:#...]  same, but for displacement in the y direction. Since these are pixels, they should be integers.
 +
note: many times images are 1392x1040 and overlap by 50 pixels, and image 0 is bottom left
 +
      image 1 is top left, image 2 is bottom right, and image3 is top right, then:
 +
      -x 0:0:1342:1342 -y 0:990:0:990  should work
 +
-o # rather than specifying -x and -y, thus just specifies the overlap (e.g., 50) and figures out
 +
the rest for you (assumes images ordered BL,TL,BR,TP - as above - and x and y overlap the same
 +
works for any size image. 
 +
 +
note: entire image name (with extension) is NOT required.
 +
note: a - in place of an image name means stdin or stdout.
 +
note: compressed images are temporarily uncompressed into /usr/tmp.

===  flood3dL  ===
 +
<nowiki>
 +
Usage:
 +
  flood3d [options] input.i2i output.i2i
 +
 +
Description:
 +
  flood3d reads in an image and outputs an image with each region's
 +
  voxels all at the same intensity (intensity = 1 for 1st region, 2 for 2nd
 +
  region, etc.). Regions are 26 connected voxels greater than the threshold.
 +
  If no output image is specified no output image will be produced.
 +
 +
Options:
 +
  -t #:    Value to threshold image (default 0).
 +
  -s #:    Value to start numbering objects (default 1).
 +
  -r x y z: Mark the region at x y z (1 indexed).
 +
            this option can be specified up to 5 times.
 +
            If z < 0, then starting points x y 1, x y 2, .. x y zdim
 +
            are used. Use z < 0 in conjunction with -c 4 or -c 8.
 +
            all such regions found are marked with the same region number.
 +
  -c #:    Do # connected flood fill (default 26).
 +
            Options are 4, 8, or 26 connected flood fills.
 +
            4 or 8 connected flood fills are for 2D flood fills
 +
            with the fill being done in x, y for each z plane.
 +
            (each slice will be done, unless -r is specified).
 +
  -m #:    only keep regions whose size in voxels is > #. Default = 0.
 +
  -b:      Output will be binary (regions counted will be 1,
 +
            regions not counted will be 0.
 +
  -q:      Quite mode, fewer messages printed.
 +
 +
Caveats:
 +
  Threshold and number of objects has to be less than 32,000.
 +
 +
Note:
 +
  Entire image name (with extension) is required.
 +
  A - in place of an image name means stdin or stdout.

===  gauss_deriv  ===
 +
<nowiki>
 +
 +
This program takes an image, blurs it with a Gaussian of
 +
specified standard deviation and then takes derivatives of the image
 +
It does all of this in the frequency domain. 
 +
 +
Usage: gauss_deriv [options] infile.i2i outfile.i2i
 +
options:
 +
  -a angle:  angle of rotation (in radians) for the x,y axes about z.
 +
default = 0.000000
 +
  -x order:  number of derivatives in the x direction.
 +
default = 0
 +
  -y order:  number of derivatives in the y direction.
 +
default = 0
 +
  -p x y z:  pixel size in microns (zsize ignored for now), default = (0.1,0.1,0.1)
 +
  -s dev:  standard deviation in spatial domain of Gaussian (in microns).
 +
  -S dev:  standard deviation in frequency domain of Gaussian (cycles/um).
 +
default = 1.000000
 +
  -e epsilon:  cutoff for Gaussian intensity calculation.
 +
default = 0.040000
 +
  -r newmax: rescale output 0-newmax. newval = (oldval-min)*newmax/(max-min). This is useful
 +
especially when all the values would otherwise be < 1.
 +
This also prints to stderr the min and max values before rescaling.
 +
  -R scale black: rescale output: newval = (oldval-black)/scale .
 +
  -v: verbose
 +
  -n: no op. just take a forward and inverse transform. For debugging.
 +
note: the entire image name is NOT required.
 +
note: compressed images will be uncompressed.
 +
note: a - in place of an image name means stdin or stdout.
 +
restrictions: only works in 2D. 3D images have each z plane processed separately.

===  i2i2mhd  ===
 +
<nowiki>
 +
 +
This program just creates a MetaImage header file (file.mhd) which can be read, in conjunction with the original
 +
i2i file, into a ITK or VTK program. NOTE: you must keep inimage.i2i and inimage.mhd together in the same directory.
 +
If specified with a .mha extension then the resulting image has both the ascii header and the data together
 +
in one file (not done yet).
 +
 +
Usage: i2i2mhd inimage.i2i inimage.mhd
 +
i2i2mhd inimage.i2i inimage.mha
 +
 +
options:
 +
-t # : set output tdim to the specified number. specify 0 if the image has no time dimension.
 +
-l : force output to be designated little endian
 +
-b : force output to be designated big endian
 +
-s dx dy dz  : pixel spacing. Some of the ACME routines may look at these values.
 +
 +

 +
  i2i2mhd test.i2i test.mhd
