As a note for everyone since this question has come up a lot, one of the many cool new features of recon-all is that it saves all of your edits, every time, by default. You have to specify with certain flags when you want it to ignore your edits (see https://surfer.nmr.mgh.harvard.edu/fswiki/OtherUsefulFlags for a list of flags). This applies to edits to manual talairach registrations, seed points for cutting planes, control points for normalization, edits to the brainmask.mgz volume, edits to the wm.mgz volume, and edits to the aseg.mgz subcortical segmentation. Every time you re-run anything that you have changed in these will be saved and used in subsequent steps. This should make re-running your subjects with a new version relatively painless.
Martin, in terms of your compatibility question, my recommendation is to always use the exact same version for a group study, its the only way you can be sure everything has been done consistently. During the time between Feb 10 (your current version) and the release there were many changes made to the code, although off the top of my head I can't make any guesses as to how this may affect your group study.

Hi, I'm currently using the freesurfer-Linux-centos4-dev20060210-full release, and I'm thinking of upgrading to the new stable release. However, I've done a lot of processing with the 20060210-release, and I'm not very keen on starting all over again with the new release. Do you recommend that I reprocess my subjects on the new stable release before doing a group study, or are they similar enough in terms of results, so that I don't need to? In case I do need to run everything over, which steps do I need to rerun (certainly not all?), and can I keep my manual edits to the brainmask- or wm-volume?
Thanks, Martin Ystad University of Bergen, Norway.
