The gray/white contrast looks terrible in that image, so it is not surprising that it can't find the G/W boundary. Is it really that bad? Have you tried adjusting the contrast in the viewer?

Dear FreeSurfer experts,
I'm seeing this type of error reoccur for around half of the subjects I've reviewed so far for a specific study. The pial and white surfaces are merging to the outermost boundary of the brain. Provided that these are older subjects, but I didn't see this error in my experience editing older subjects in other studies. Is there perhaps a preprocessing command I could perform since this error is systematic throughout the brain, not specific to a region? Attached is an example image that showed this type of mislabeling (tried attaching more images but there were size limits).
Thank you for any input!
