External Email - Use Caution Thanks -- how much additional processing would the norm.mgz images have gone through in the longitudinal pipeline compared to base ? It seems they are all in the SST space which leads me to think there is at least additional interpolation -- but are there further processing that would affect the intensity distributions ?
