External Email - Use Caution
It is hard to say from that image because of the aseg, but it looks like the white surface is not extending far enough and so the pial surface starts too far away to get all the way out. You might need some control points in the WM in that area_______________________________________________

Sorry for the very late reply and not explaining the problem well in the first place. I would still appreciate your assistance if possible.Like some other threads that are on the archive, I was experiencing the problem where the pial surface wasn't getting all of the gray matter. None of the threads have seem to been resolved so I hope I could get some help. Would it be alright if I sent the subject directory for you to take a look?Thank you.

Can you be clearer as to what the problem is? If it is that the cortical segmentation (red voxels) don't seem to follow the white/pial surfaces, then there is nothing to worry about because the aseg is not expected to have a good cortical segmentation (see aparc+aseg.mgz instead)._______________________________________________

Hello FreeSurfer experts,
I am trying to figure out how to fix the segmentation so that the cortex is properly included.I have had this problem with several subjects, especially in the temporal lobe regions.
I have tried tkmregister but it unfortunately didn't change anything. I am in the middle of using control points to try to fix this problem but it hasn't been ideal as it is requiring a lot of control points. Do you have any ideas on how to fix this?
I have attached an image of what the problem looks like below. Please let me know if you need anything else.
Thank you!
