Hi Fellow FreeSurfers, How do you calculate Brain Volume in FS5.1? In 4.5 there was the BrainSegNotVent statistic in aseg.stats, but I'm not seeing that in 5.1. I did find something about the SupraTentorialVol, but that would exclude the brainstem and cerebellum. I'm not sure if that also includes the ventricles, but that would need to be factored in as well. I did some math to compare values between 4.5 and 5.1. I took the SupraTentorialVol from 5.1, added Left-Cerebellum-White-Matter, Left-Cerebellum-Cortex, Right-Cerebellum-White-Matter, Right-Cerebellum-Cortex, and Brain-Stem. I then subtracted out the ventricles (Left/Right-Lateral-Ventricle, Left/Right-Inf-Lat-Vent, 3rd/4th/5th-Ventricle). The end result of my 5.1 volume is 51,429 voxels larger than the value from 4.5.
