Estimation of brain's tissues anisortopy using Brainsuite Diffusion Pipline
Authors: Takfarinas Medani, Francois Tadel, Anand Joshi and Richard Leahy
[TUTORIAL UNDER WRITING: NOT READY FOR PUBLIC USE]
Describe brainsuite here : here we will describe the process of the brain tissues anisotrpy estimation and the different functions that brainstorm offers.
This tutorial explains how to use Brainsuite to estimate the anisotropy of the brain tissues.

The scope of this page is limited to a basic example (head model with 3 layers), more advanced options for head model generation and forward model options are discussed in the tutorial about FEM mesh generation. We assume that you have already followed the introduction tutorials (or at least the head modeling tutorial), we will not discuss the general principles of forward modeling here.
