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?
