Hi Bruce, I'm using v5.3.0. Does this version do well with patients with large ventricles? Two cases I ran seemed to do well with the ventricles, but some others seem to be running into some errors (which I haven't had the time to work out yet). So in your opinion, to get our desired measures of total gray matter and ventricular volume, we would not need to create our own atlas?
Side question: Is there any literature on/do you happen to know what the margin of error for a measure like total gray matter (taken from the aseg.stats header) is in Freesurfer?
