Hi Bruce,
When I have a look in the recon-all script I see that it is tested if there are voxels present in wm.mgz with value 1 or 255. Both indicate wm editing. The comment in recon-all says that 1 means remove and 255 means add. And concerning my second question: are these edited voxels correcly processed with the option autorecon2-wm and subsequently with longitudinal processing?
Cheers, ed

Hi Ed,
yes, although we reserve the values under 5 I think for editing changes, I believe we only use 1 at the moment.

Hi,
From what I can read in the wiki about wm editing, I understand that edited wm voxels have values of either 255 (added) or 1 (removed) and no other values. These are stored in the file wm.mgz. Is that correct? Before processing a lot of data I want to be sure that running recon-all with the option autorecon2-wm will recognize these voxels, also during longitudinal processing. Can you confirm this.
