Hello,
I am having a few issues with editing the pial surface in freeview. It appears as though the edits I make to the brainmask are not being taken into account when I re-run recon-all. I work on a MacBook Pro and have been using "shift+click" to delete voxels at a brush value of 1 and then saving the brainmask.mgz back into the mri folder. When making edits to the brainmask I have the brainmask highlighted. Upon clicking save, the mri folder contains both brainmask.mgz and brainmask.mgz~ (The version with a ~ seems to indicate the older version of the file based on modification time).
Additionally, the edits that I make to brain.finalsurfs.manedit.mgz for pial surface that has extended into the cerebellum seems to not be taken into account when I re-run recon-all. I have been making a copy of brain.finalsurfs.mgz, pasting it into the mri folder, and renaming it brain.finalsurfs.manedit.mgz. I then load this volume and make edits to it according to the same specifications as the brainmask.mgz. Shouldn't I be able to see changes made to the pial surface in the brainmask.mgz from edits I make to the brain.finalsurfs.manedit.mgz after running recon-all? Neither the brainmask.mgz nor the brain.finalsurfs.mgz take into account the edits I've made on brain.finalsurfs.manedit.mgz. I'm not sure if I'm deleting voxels incorrectly or saving incorrectly. I've tried to troubleshoot several times and keep encountering similar issues.
The version of FreeSurfer that I am working from is: freesurfer-i686-apple-darwin9.8.0-stable5-20110525 My editing interface looks slightly different from the current version explained on the freesurfer wiki. I do not have an option to select recon-editing. Adding control points, however, has been successful. I have been using the command recon-all -autorecon2 -autorecon3 -s subj001
Any help getting to the bottom of this would be greatly appreciated!
