Generate an appropriate response function from the image data for spherical deconvolution
sh2response [ options ] SH mask directions response
SH: the spherical harmonic decomposition of the diffusion-weighted images
mask: the mask containing the voxels from which to estimate the response function
directions: a 4D image containing the direction vectors along which to estimate the response function
response: the output axially-symmetric spherical harmonic coefficients
The spherical harmonic coefficients are stored according the conventions described the main documentation, which can be found at the following link:
-lmax value specify the maximum harmonic degree of the response function to estimate
-dump file dump the m=0 SH coefficients from all voxels in the mask to the output file, rather than their mean
-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.
