# 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.

## 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.
