Subject: Re: [Freesurfer] Tracula: anatomical priors
Hi Heidi - TRACULA does not use deterministic constraints like pre-defined ROIs to reconstruct the tracts. For each point along a tract (and not just the end points), it has a prior probability (that it has computed from the atlas subjects) that a tract goes through each of the aparc+aseg labels, or goes next to (in the L, R, A, P, etc direction) each of the aparc+aseg labels.
Best,
a.y

Dear FreeSurfers,
Where can I find the anatomical ROIs from the aparc/aseg (end and begin points) that are being used to reconstruct the tracts in Tracula?
Many thanks
Heidi
