ttest(1)					       The Computational Morphometry Toolkit						  ttest(1)

NAME
       ttest - T-tests

SYNOPSIS
       ttest [options] imageX0 [imageX1 ...] -- imageY0 [imageY1] ...  ttest [options] --symmetric imageX0 [imageX1 ...]

DESCRIPTION
       Pixelwise tests of statistical significance. Also compute correlations and z-scores

OPTIONS
   Global Toolkit Options (these are shared by all CMTK tools)
       --help
	    Write list of basic command line options to standard output.

       --help-all
	    Write complete list of basic and advanced command line options to standard output.

       --wiki
	    Write list of command line options to standard output in MediaWiki markup.

       --man
	    Write man page source in 'nroff' markup to standard output.

       --version
	    Write toolkit version to standard output.

       --echo
	    Write the current command line to standard output.

       --verbose-level <integer>
	    Set verbosity level.

       --verbose, -v
	    Increment verbosity level by 1 (deprecated; supported for backward compatibility).

       --threads <integer>
	    Set maximum number of parallel threads (for POSIX threads and OpenMP).

   Main Options
       --log, -l
	    Use log data for testing

       --abs, -a
	    Use absolute data for testing

       --abs-out, -A
	    Generate absolute (unsigned) data

       --invert, -i
	    Invert data, i.e., subtract from 1.0

       --short, -s
	    Convert probabilities to short (and scale by 1000)

       --paired, -p
	    Compute paired t-test [default: groupwise]

       --cross-correlation, -c
	    Compute paired cross-correlation

       --zscores, -Z
	    Compute z-scores of test (y) distribution averages

       --text, -t
	    Text file input and output rather than image files.

       --mask <string>, -m <string>
	    Mask file name [Default: NONE]

       --outfile <string>, -o <string>
	    Output file name [Default: ttest.nii ]

       --tstats-file <string>
	    T-statistics output file name (for correlation: p-value output file) [Default: NONE]
