Hi Cat,You'll need to rerun those subjects with 5.1 to be able to use the longitudinal analysis in 5.1.
You can also find a detailed explanation on how to go about edits here: https://surfer.nmr.mgh.harvard.edu/fswiki/LongitudinalEdits Allison On Wed, 18 Apr 2012, Cat Chong wrote:
Dear Freesurfers: We have a large group of subjects (for which we have two time-points) that were run through the recon-all stream using 5.0. We have done no manual editing yet. We would like to do a longitudinal analysis of these subjects using 5.1 by comparing both time-points for each subject. Is that a possibility using 5.1? Also, at what point should I correct for topographical defects, or make edits to the white matter or brain mask volume? Should I edit both time-points separately first and then initiate the longitudinal analysis? If so, could I do the manual editing using 5.1? thank you very much for your help, cheers, cat
