Diffusion Tractography

[graph] This pipeline performs DTI tensor model fitting and tractography.

It is based on UCL Camino.

It depends on the anatomical and the DTI pre-processing pipelines.

Steps:

  1. DTI fit.
  2. ROIxROI atlas-based deterministic tractography.
  3. Connectivity matrices:
    1. one with the number of tracts for each pair of ROIs, and
    2. the other with average tract FA values for each pair.
