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
calculations.
- -ceil max
- An upper bound for ranges of data to include in statistic
calculations.
- -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.
