Dear FreeSurfer Team,

We are editing some longitudinal data using FreeSurfer 7.4.1.

I am not sure how to fix the following issue (see the attached pictures).

The white surface (blue line) almost touches the pial surface because some of the voxels are "too bright" at the edge, so they were misidentified as white matter.

Which volume should I edit to fix this?

I was thinking about deleting these voxels from the brainmask but that might lead to excluding/deleting gray matter incorrectly. Or maybe I could delete these voxels from the white matter. I was also considering cloning some of the surrounding voxels somehow to make this area less bright.

Thank you, 

Eszter
