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

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.
