We're running QA on Freesurfer's aseg and aparc+aseg volumes. On the aparc volume we're noticing fairly large unknown regions in what should be entorhinal cortex, specifically where it comes up against the hippocampus and amygdala. The aseg volumes label these unknown regions as cortex. I've searched the archives and haven't been able to find anything similar from recent years. I've attached some axial screenshots of the raw T1, the aseg and the aparc+aseg.
