Hi,
Are there any ways to fix underinclusion of gray matter cortical edges when the white matter is fine? Attached is a picture.
Thanks, Christina
Hi Christina
it's tough to tell from just a single image, but it looks to me like you are missing a bunch of white matter. Can you tell us more about the scan?
The typical way you would fix this is by setting some thresholds in mris_make_surfaces using the expert options. Probably max_csf should be lower. If you upload the subject we will take a look

You could also add a lot more voxels to the wm.mgz (beyond what is wm) and depending on the source of the problem, that could fix it.

dear all, i am new on Mac and freeSusrfer. I have installed freesurfer through the tutorial. Is there any tutorial how to run on Mac. Is there any method to extract stats on excel or spps? The .mgz file shows the brain radiologically (r/l) or vice versa John Papatriantafyllou
