I'd like to compute %GM, %WM, %CSF wrt ICV (eTIV)...including cerebellum gray/white.
Are the values returned by mris_wm_volume and mris_volume for cortical surfaces only (excluding cerebellum)?
So, in this case... 1) are the values in aseg.stats appropriate for both cerebral and cerebellar fractions? 2) should a combination of cortical GM & WM from mris_volume be added to the cerebellar gm & wm values reported in aseg.stats to get TOTAL_GM and TOTAL_WM? 3) is it true that CSF= ICV - GM(cerebral and cerebellar) - WM(cerebral and cerebellar)
Any advice is greatly appreciated...
Many Thanks, Jenifer Juranek
