Hi Michael,
Yes, it is strongly recommended that all data be processed with the same
version of FreeSurfer.
Also, the 'base' and 'long' steps of the longitudinal processing should be
re-run after adding a new timepoint.

Subject: [Freesurfer] Longitudinal FS Processing
External Email - Use Caution
Hello,
I hope that I am sending this question to the right place. Please let me know
if not.
I need to do longitudinal FS processing for a study that originally had 3
timepoints (data was processed a couple of years ago using FS for these 3
timepoints). Part 2 of the study has begun, which consists of 1 additional
timepoint. What would be the best approach for using FS to process the data at
this new timepoint given that the data for the other 3 timepoints have already
been processed? Do I need to be careful with using different versions of FS?
Thank you!
Michael
