Sorry Corinna I meant to answer this the first time but it slipped through the cracks. I doubt there is much you can do if there is that big a lesion. If the topology is wrong and you can't see tissue in those regions it's going to be very hard Bruce On Wed, 10 Feb 2016, Corinna Bauer

Re: [Freesurfer] pial edits in subject with severe atrophy

Thanks, Bruce. In an earlier thread from '09 with a similar problem ( https://mail.nmr.mgh.harvard.edu/pipermail/freesurfer/2009-May/010554.html), it was mentioned that there was a method being developed to edit the surface mesh. Is that option still available and would it help? Since this step in
