Hello -
I have two questions:
1) I noticed on wm.mgz volumes that were segmented properly, that even when the ventricles were automatically filled in, on some slices they are somewhat patchy (partially filled in with white, with some black/blank voxels).
Do these patchy wm fill-ins require manual fill-ins to make them entirely opaque?
I went through the tutorial, and it was not clear whether a patchy fill-in required a correction or not.
2) What is the best automated measurement that can be used to normalize an individual's cortical segmentation volumes for between subject comparison? We have been using gray+white volumes (why we need the ventrical volume processing to be consistent) - but not sure if ICV would be better individual normalizer.
Thank you for your time - Sherri
