shconv

Synopsis

Perform a spherical convolution

Usage

shconv [ options ]  SH_in response SH_out
  • SH_in: the input spherical harmonics coefficients image.
  • response: the convolution kernel (response function)
  • SH_out: the output spherical harmonics coefficients image.

Description

The spherical harmonic coefficients are stored according the conventions described the main documentation, which can be found at the following link: https://mrtrix.readthedocs.io/en/3.0_RC3/concepts/spherical_harmonics.html

Options

  • -mask image only perform computation within the specified binary brain mask image.

Stride options

  • -strides spec specify the strides of the output data in memory; either as a comma-separated list of (signed) integers, or as a template image from which the strides shall be extracted and used. The actual strides produced will depend on whether the output image format can support it.

Standard options

  • -info display information messages.
  • -quiet do not display information messages or progress status; alternatively, this can be achieved by setting the MRTRIX_QUIET environment variable to a non-empty string.
  • -debug display debugging messages.
  • -force force overwrite of output files (caution: using the same file as input and output might cause unexpected behaviour).
  • -nthreads number use this number of threads in multi-threaded applications (set to 0 to disable multi-threading).
  • -config key value (multiple uses permitted) temporarily set the value of an MRtrix config file entry.
  • -help display this information page and exit.
  • -version display version information and exit.
