Hi Allison,

Upon a closer look, it appears that there were still some corrections to be 
made for the subject whose 5.0 corrections "were preserved," just not as many 
edits for this subject as the others. (The difference in the amount of edits we 
need to make were significant, however.)

For one subject, I ran [recon-all -all -s subjid] in 5.1, the edits carried 
over in 5.1. But then I took this subject again and ran [recon-all -all 
-clean-bm -subjid] with brain.finalsurfs.manedit.mgz in the subj/mri/ directory 
and when I checked this subject in tkmedit the next morning, I had the same 
issues with the edits not being preserved. Have you observed these results with 
running -clean-bm in your lab?

Best,

and recreating cerebellum in brainmask

Hi Vy,
I'm not sure why that only seems to be working sometimes. Can you send me
a case it did work on and a case it didn't work on?
