NAME

       average_images - Average images

SYNOPSIS

       average_images [options] image0 ...

DESCRIPTION

       This  tool  computes  pixelwiase  average,  variance, standard deviation, z-score, or entropy images from a list of user-provided intensity
       images.

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
       --mode
	    Mode of averaging operation Supported values: "avg", "var", "stdev", "zscore", "entropy", where the default is "avg", or  use  one	of
	    the following:

	    --avg
		 Compute average (i.e., mean) image [This is the default]

	    --var
		 Compute variance image

	    --stdev
		 Compute standard deviation image

	    --zscore
		 Compute z-score image

	    --entropy
		 Compute pixel-by-pixel population entropy image

   Data Preprocessing
       --log, -l
	    Apply log to input data

       --abs, -a
	    Use absolute input values

       --normalize-mean-stdev, -n
	    Normalize image intensities using means and standard deviations

       --set-padding-value <double>
	    Define padding value in input images [Default: disabled]

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

       --type
	    Scalar data type of output image.  Supported values: "float", "double", where the default is "float", or use one of the following:

	    --float
		 Single-precision float.  [This is the default]

	    --double
		 Double-precision float.
