voxel2fixel

Synopsis

Map the scalar value in each voxel to all fixels within that voxel

Usage

voxel2fixel [ options ]  image_in fixel_directory_in fixel_directory_out fixel_data_out
  • image_in: the input image.

  • fixel_directory_in: the input fixel directory; used to define the fixels and their directions

  • fixel_directory_out: the fixel directory where the output will be written; this can be the same as the input directory if desired

  • fixel_data_out: the name of the fixel data image.

Description

This command is designed to enable CFE-based statistical analysis to be performed on voxel-wise measures.

Fixel data are stored utilising the fixel directory format described in the main documentation, which can be found at the following link:
https://mrtrix.readthedocs.io/en/3.0.4/fixel_based_analysis/fixel_directory_format.html

Options

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.
