SHCoefficientsPower

USAGE:

   SHCoefficientsPower  [--returnparameterfile <std::string>]
                        [--processinformationaddress <std::string>] [--xml]
                        [--echo] [--debug] [-p] [--nt <int>] [--sh <int>]
                        [--power <double>] [--] [--version] [-h]
                        <std::string> <std::string>


Where:

   --returnparameterfile <std::string>
     Filename in which to write simple return parameters (int, float,
     int-vector, etc.) as opposed to bulk return parameters (image,
     geometry, transform, measurement, table).

   --processinformationaddress <std::string>
     Address of a structure to store process information (progress, abort,
     etc.). (value: 0)

   --xml
     Produce xml description of command line arguments (value: 0)

   --echo
     Echo the command line arguments (value: 0)

   --debug
     debug (value: 0)

   -p,  --progress
     show progress of processing (value: 0)

   --nt <int>
     Number of threads. If it not positive, then the default number for
     multiple threads is used. (value: -1)

   --sh <int>
     SH Rank for output SH coefficients. It is needed for refitting if the
     power is not 2 or 1. If not set, it is set as the rank of the input SH
     image. (value: -1)

   --power <double>
     Power argument. If the power is 2, we have closed form. For other
     power number, we use a numerical fitting of the powered spherical
     function. (value: 1)

   --,  --ignore_rest
     Ignores the rest of the labeled arguments following this flag.

   --version
     Displays version information and exits.

   -h,  --help
     Displays usage information and exits.

   <std::string>
     (required)  Vector image that contains the SH coefficients.

   <std::string>
     (required)  Vector image that will contain the rotated SH
     coefficients.


   Description: Power of a spherical function represented by SH basis.

   Examples:

   SHCoefficientsPower odf.nii.gz odf_power.nii.gz --power 2.0
