This section of the tutorial This section of the tutorial will teach you to extract Statistical measures along the major White Matter tracts reconstructed by Tracula. There are two types of statistics files that are output for each White Matter Tract
 * path.overall.txt - This file gives Diffusion measures along the whole WM tract
 * path.byvoxel.txt - This files gives Diffusion measures for each voxel along the WM tract.

To view the statistics files from Tracula for for the subject Diff001 (Left Cortico-Spinal Tract), type the following in the terminal
----
{{{

These two files that can be used for extracting statistics to perform GLM analysis.

This can also be converted into a table using tractstats2table for doing group analysis using mri_glmfit or any other statistical software (SPSS, Excel, Statview etc).

Tract Statistics

  • path.overall.txt - This file gives Diffusion measures along the whole WM tract
  • path.byvoxel.txt - This files gives Diffusion measures for each voxel along the WM tract.
