Hi Derek,

you have to be careful about window levels and such, and make sure it's not dura.

Hello FreeSurfer Team,

I am wondering how to add cortex to the pial volume that is already present in the brainmask volume. When I look at the brainmask volume, there is visible cortex located outside the red "pial" line. I have already added white matter control points and corrected all white matter defects. I am wondering if you have any tips for me. I apologize if this is a repeat question but I couldn't find anything in the wiki about correcting this type of error.

Thank you, Derek
