Use MrTrix with vistasoft

This page describes how to use MRTrix with vistasoft.

MRtrix is a set of tools to perform diffusion-weighted MR white-matter tractography in a manner robust to crossing fibers, using constrained spherical deconvolution (CSD) and probabilistic streamlines. This page describes how to install and use this package with vistasoft. Elsewhere, we describe how to run MRtrix on local data. We often use MRtrix along with the Linear Fascicle Evaluation (LiFE) technology. We describe how to run LiFE on a separate page .

This page still assumes MRTrix version 2. Now MRTrix team developed the later version of the MRTrix, MRTrix version 3. The functions in vistasoft is only compatible with MRTrix version 2 now.

See [MRTrix Exampmles](MRTrix Examples) for a example usage with vistasoft.
