Dear Experts,

I am occasionally noticing some 'pinching' on the inflated brain surfaces around the temporal lobe pole. When I check the brainmask.mgz files, the raised areas are due to a 'bubble' of pial surface forming on top of pial surface. Upon checking white matter and grey matter boundaries, the pial surface should really not be separated as a "bubble", but should in fact be all one surface. What would you suggest would be the best way to fix this? The white matter seems to be fine.

Best Regards,

Catherine
