Hi Andreas, it is not the same method but somewhat related. The method assures that total area (or volume) is preserved when mapping between subjects. How much detail do you need? doug

Hello FreeSurfers,
after reading this [1] paper about measuring surface area, i realized i don't know what the default way of measuring surface area is in FreeSurfer. Is it similar to what's described in the paper? Could you point me to the right documentation or publication? Forgive me if i've overlooked it, i found something for thickness, but not for area. To clarify, i don't mean parcellation-based areas, i mean the measure that i find in /surf/hemi.area.
thanks, regards, Andreas
