Dear FreeSurfer experts,
I have run a longitudinal study considering multiple time points (7 scans/subject on average) with FS 5.1. However, I am interested in the percent changes between two time points only (between 0 and 6 months and between 0 and 1 year). Should I run the longitudinal stream from step 2 (template) two more times (1.- considering only 0 and 6 months scans and 2.- considering only 0 and 12 months scans) or is it correct even if my templates were built with all the time scans together?
Thank you for your help, Yolanda
