Dear TRACULA users,

I ran near 100 subjects through the standard (cross-sectional) TRACULA pipeline. Some of them (about 70) have also a longitudinal DTI scan 1-year after the already processed scans. I would like to run longitudinal TRACULA to obtain for those 70 subjects longitudinal changes in FA/MD in the major white matter tracts.

My question is: should I specify in the longitudinal dmrirc file that the 80 baseline subjects have already been processed? Will tracula already know it and not re-compute?  Could you please provide a fully-working sample dmrirc file for this scenario so I could see the format?

I’ve found this pdf https://ftp.nmr.mgh.harvard.edu/pub/docs/TraculaNov2013/tracula.workshop.v.pdf only but didn’t manage to solve my questions.

Thanks a lot in advance,
