Hi Allie,
pial surface which looks like this can only be corrected by correcting the wm.mgz. Also I would suggest to try and fix the cerebellum and see if it corrects the surfaces as well. Since part of the cerebellum is stripped off, it's probably affecting the segmentation as well but I could be wrong. what version of freesurfer are you using.

Hi Sita,
Can I still add voxels to wm.mgz even though the points would be outside
even the pial boundary?
Thanks

Hi Allie,
This probably needs white matter edits but it's hard to tell from one
slice. Please refer to our white matter edits wiki and toplogical defects
wiki and see if it helps in fixing the errors in your datasets. Also it
looks like part of the Cerebellum is stripped off. You might want to correct
that as well.

Hi,
Once processed, several of my subjects have had errors around the
occipital
lobe. Attached is an example. I've already tried editing brainmask.mgz and
running recon-all, but as you can see, this didn't change the pial or wm
borders. What can I do to fix this?
Thank you,
