Hi Skyler - I would *highly* recommend using the version of tracula in 5.3, as there have been improvements in both performance and speed.
You can check the DWI to anatomical registration by overlaying the aparc+aseg from the dlabel/diff directory (which is in diffusion space) on the FA map. Does that look ok?

Hi Anastasia,
We're using 5.1. It's likely poor registration. The aparc+aseg. looked fine. Is there anything to do about poor registration?
Thank you for the fast reply. Truly appreciated. Skyler

Hi Skyler - Are you using freesurfer 5.1 or 5.3?
Most likely this issue is due to poor registration, either from the individual DWI to the individual T1, or from the individual T1 to the template space. Or it could be that there is a problem with the aparc+aseg.

Hi all,
I've been running DTI using tracula (fs version 5) for over 1 week on 2 subjects. It appears that it is having difficulty finding satisfactory control point fit and has attempted over 1600 tries. Any help is greatly appreciated. See error below:
