Hi all,
From my understanding from the log files, the subfield segmentations (and in general the aparc.mgz) relies on the norm.mgz (which is based off the brainmask.mgz). What if hypothetically, you have a not so good segmentation of the cerebral cortex, but willing to individually qc the subfields for the hippo, amyg and thal to see whether they are worth including in an analysis? I don't know if you would inherently discard a subject in a subfield analysis if it has a bad cerebral cortex segmentation (e.g ring artifacts) since the subfield segmentation retrieves some sort of cerebral cortex measurement in its calculations
