Hi Ri - Tracula reconstructs 18 specific tracts, listed in step 14 here: https://surfer.nmr.mgh.harvard.edu/fswiki/FsTutorial/Tracula
Just like you cannot use freesurfer to find a region that's not included in the freesurfer atlas, you canot use tracula to find a tract that's not included in this list.
Hope this helps, a.y

Hello All,
I am a total newbee in dt-recon and tracula. So sorry if this is a very basic question.
From what I gathered so far-
TRACULA uses the aparc+aseg.mgz from the FreeSurfer recon (T1-weighted volume) as ROIs to construct the tracts and also constructs a few tracts by default.
Is there a way of defining our own ROIs and get tracts ?
Thanks
Ri
