SHCoefficientsPower
===================

.. code-block:: none

  
  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
