Hi, I have been using control points to correct excluded white matter and ran into the same problem as Peter, https://mail.nmr.mgh.harvard.edu/pipermail//freesurfer/2012-July/024771.html , in that the opposite hemisphere's boundaries recede after control points are added and then recon-alled. Has this issue been resolved in 5.2 or 5.3? Thanks, Lior Zwanziger
