Hi Susan - Good to hear that you get good results for most of your subjects. Have you checked the aparc+aseg and the diffusion-to-anatomical registration for the subjects that are failing? I'd check the aparc+aseg_mask (in the dlabel/diff directory) over the FA map to see if there are any holes or misregistration.

Hi FreeSurfers and Anastasia, TRACULA is working great for me, generating tracts for a sample of 20 subject brains I'm working with. However, for 3 of the brains, I'm receiving incomplete and poorly formed tracts. I've re-run trac-all at least 2x on each subject in case there was a mistake in my original configuration. However, I am reproducing the same results. Does anybody have an idea why I would see these "spotty" tracts? Thank you for all your help! -- Susie Kuo NIH
