[Freesurfer] TRACULA - failed corpus callosum forceps major

Hello,

I have tried out running TRACULA on 20 subjects. It all seemed to work well except that in 8 of the subjects the corpus callosum forceps major was either missing or was a very small cluster. The same happened for the temporal SLF of 2 subjects.

I read previous posts related to this and tried re-running the affected subjects with set reinit =1. However, the results were very similar to before. I have checked the registrations and they are not perfect, but not wildly inaccurate.

Are you able to suggest any options for me to try? I have attached the dmrirc file I used for the first run (called dmrirc-original) as well as the one for re-running the subjects whose CC was not segmented (called dmrirc).

Thank you.

Best wishes, Clare
