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.

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
