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
