[Freesurfer] Tracula: a single curve for some tracts

Dear Anastasia, One quick question. I have run Tracula and found there was only one single curve for some tracts. But other tract went well I tried setting reinit parameter to 1 and rerunning "trac-all -prior" and "trac-all -path" but didn't get improved, e.g., the right UNC was a single curve (see attached). I also checked the initial seeds of right UNC (i.e.,endpt1.pd.nii.gz and endpt2.pd.nii.gz) and found those seeds were visually not correct when loaded to FA image. I guess maybe the reason of the single curve problem. Is there anyway to fix this problem? Looking forward to hearing from you. Thank you very much.

Best, Xiaofu
