Hi Catherine - Yes, for now treat each time point as a different subject for trac-all purposes. (You can pass the time points' recon-all directories either before or after longitudinal processing.) However, there may also be a longitudinal version of tracula coming soon - but you didn't hear this from me...

Hello Experts,

Please forgive another question. I have run 59 people through the recon-all freesurfer longitudinal stream with 2 timepoints (tp1id, tp2id). I want to run these subjects through "tracula" next, since the same people also received repeated Tensor imaging. To process everybody through tracula, I would use each person's original (cross-sectional) recon-all output and not the template or -long recon-all output, correct?

Best regards, Catherine
