There is a excellent segmentation in -surfs after editing the pial and run -autorecon-pial by tkmedit and recon-all respectively. Some voxels was removed from the brainmask.mgz in editing the pial. However the -aseg image still have those voxels which I have removed from the brainmask.mgz. This is why? Do I need to run -autorecon3 to fix the aseg?

There are brainmask.mgz(pic 1) and aseg(pic 2) snapshots in the attachment.
