Dear experts, I am using freesurfer V5.3. I am trying to fix some error in freesurfer outputs. The issue is that grey matter misclassified as white matter in temporal lobe (lh). I tried to edit Wm.mgz and re-run with -autorecon2-wm, but it did not work. Looking at the brainmask.mgz, white matter boundary includes area with intensity normalization less than 60-50. Any suggestion?

I appreciate any help, Maryam
