NAME
minccmp - compare one or more minc file using comparator operators
SYNOPSIS
minccmp [<options>] <in1.mnc> <in2.mnc> [<inn.mnc> ...]
DESCRIPTION
minccmp will calculate simple statistical measures between two minc
files or more by comparing all subsequent files to the first. The
results for each subseqent file are then returned in order. By default
all statistics are calculated. If specifitc statistics are requested
via a command-line option, then only the requested statistics are
printed.
A very useful feature of this program is the ability to restrict the
set of voxels included in the statistic calculation, either by
restricting the range of included values (-floor, -ceil or -range), or
by using a mask file (-mask) with a restricted range.
The comparison statistics available in minccmp are given below. Note
that two of these (-xcorr and -zscore) are a very close approximation
to what is used in minctracc.
OPTIONS
Note that options can be specified in abbreviated form (as long as they
are unique) and can be given anywhere on the command line.
General options
-clobber
Overwrite an existing file.
-noclobber
Don't overwrite an existing file (default).
-debug Dump a lot of extra information (for when things go haywire).
-verbose
Print out extra information (more than the default).
-quiet Print out only the requested numbers
-max_buffer_size_in_kb size
Specify the maximum size of the internal buffers (in kbytes).
Default is 4 MB.
-check_dimensions
Check that all input files have matching sampling in world
dimensions (default).
-nocheck_dimensions
Ignore any differences in world dimensions sampling for input
files .
Volume range options
-floor min
A lower bound for ranges of data to include in statistic calcu‐
lations.
-ceil max
An upper bound for ranges of data to include in statistic calcu‐
lations.
-range min,max
A lower and upper bound for the ranges of data to include in
statistics.
-mask filename.mnc
Name of file to be used for masking data included in statistic
calculations.
Basic statistics
-all Compute all statistical measures. This is the default.
-ssq Print the Sum Squared Difference between two input files
SSQ = Sum( (A-B)^2 )
-rmse Print the Root Mean Squared Error between two input files
RMSE = sqrt( 1/n * Sum((A-B)^2))
-xcorr Print the Cross Correlation between two input files
XCORR = Sum((A*B)^2) / (sqrt(Sum(A^2)) * sqrt(Sum(B^2))
-zscore
Print the z-score difference between two input files
ZSCORE = Sum( |((A - mean(A)) / stdev(A)) -
((B - mean(B)) / stdev(B))| ) / n
Generic options for all commands:
-help Print summary of command-line options and exit.
-version
Print the program's version number and exit.
