Hi Lars – That’s correct, you don’t need to run cross-sectional TRACULA first, you just need to run longitudinal recon-all before you run longitudinal TRACULA, and it expects that the time points and base template subject IDs are the same for recon-all and for TRACULA. It sounds like the time points’ MNI registrations were not created, which is something that happens before the command that gives you the error. Is there an error in the time points’ trac-all.log files?

Subject: [Freesurfer] longitudinal TRACULA

Hi,

I've run cross-sectional TRACULA on one subject, three different timepoints. Now I'm trying to run a longitudinal analysis on the same subject's 3 timepoints. My understanding was that for TRACULA, unlike for morphometry, I don't need to first run cross sectional before longitudinal, the only requirement is that I have a longitudinal dmrirc file that specifies the timepoints with their corresponding files.

It crashed with these error messages:

Any idea what went wrong here?


Thank you!
