[Freesurfer] Gray Matter Errors, Ignored Areas

Hi everyone.

I have a little trouble. First of all, I performed the recommended reconstruction. When I inspect the results, the boundaries of white matter are correct, but the Gray Matter is incorrectly understimated.

As I show in the attached file, large parts of gray matter were ignored on the pial surface.

It is extrange, because when I inspect the aseg file, the voxels of those areas are correct classified as cortex.

I have been searching how to fix it, but I was unable to find how to do it on the troubleshooting tutorials. When this problem appears in white matter tissue, can be corrected with control points. What can I do when the same problem is in gray matter?

Thanks.[image: Imágenes integradas 1]
