Hi matt
Does the parcellation look correct? If so you might be ok if you stay away from the affected regions. It's hard to tell from one slice.

As you can see, the unprocessed MRI file has an intensity problem in the temporal lobe, almost like a flashlight is lighting it up. When FreeSurfer processes this part of the brain it fails to detect it. My question is a) is this data still usable? We aren't actually looking for any effects in this area of the brain, but are worried that it is a bigger symptom of problematic data and b) if this data is still usable, is there anything we can do to work around it?
