       average_images - Average images


       average_images [options] image0 ...


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


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

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

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

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

            Write toolkit version to standard output.

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

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

                 Compute variance image

                 Compute standard deviation image

                 Compute z-score image

                 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 ]

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

                 Single-precision float.  [This is the default]

                 Double-precision float.
