Hi Hengameh
What does the pial surface look like in the volume? If it is grabbing dura you would erase it and rerun part of recon-all.
Cheers Bruce

External Email - Use Caution Hello,
I hope you are well.
I was wondering if there is an easy way to correct for missegmentation of the grey matter parcellation. For example, would it be possible to correct for the overestimation of the pre-postcentral gyri (see picture below)? Since it seems as if the parcellation is extending into the meninges.
Warmly, Hengameh
