Hi Doug,

so you 1. edited the cross sectionals and surfaces look fine (make sure you edit the brain.finalsurfs.manedit.mgz file, which you create as a copy of the brain.finalsurfs.mgz) 2. checked/edited the base and surfaces look fine too 3. ran the longitudinal from scratch (w/o any edits)

and then in the long, the surface looks not good?

Edits should automatically be copied from cross->long (if the manedit file exist). Surfaces are taken from the base to initialize longitudinal processing. That is why both step1 and step2 above are important. Step3 is a good idea to make sure that the longs are not polluted by some earlier edits. For example edits from cross are only copied over if the long has no manedit file, else only the edits in the long will be used. (I think this also answers some of the questions in the archive mail 1 you cite below, the archive mail 2 is a question about cross sectional processing, but I think there the problem is that brainmask.finalsurfs.mgz was edited directly, not the manedit file, so edits probably get overwritten).

I also have the feeling that we fixed something about the editing in longitudinal processing after 5.1, but cannot find it documented on the wiki (so not sure). You may want to try to run this with 5.3 if it does not work with 5.1

Best, Martin

Dear Freesurfer experts,

I have a question regarding longitudinal edits. Specifically the brain.finalsurfs.manedit.mgz file and the longitudinal processing stream in Freesufer 5.1 on a Mac (freesurfer-i686-apple-darwin9.8.0-stable5-20110525).

The problem that I am having is that the edits saved in the brain.finalsurfs.manedit.mgz file do not carry over when processing longitudinally.

Previous posts have addressed this topic, but have not (to my knowledge) solved the issue. Please see the threads from the Freesurfer archive below for a brief context:

Please let me know if more information is needed to understand the issue.

Any insight/ideas regarding this issue would be greatly appreciated!

Thanks,

Doug
