Hi,
So far, I have results from autorecon1 & -subcortseg. The aseg.stats that are obtained following these procedures contain measures of L & R-Cerebral-White-Matter and Cerebral Cortex. If I created masks (bitmaps) using these labels in FreeSurfer, would they be equivalent to whole-brain WM and GM, or do I need to use maps/surfaces created further along in the FreeSurfer processing stream (if so, which would be accurate)?
In general, how would these differ from the tissue segmentations obtained using FSL-FAST?
Thank-you for your help,
Julie
