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


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.


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


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).
  • -help display this information page and exit.
  • -version display version information and exit.
