Hi,

I was just wandering exactly how the grey matter volume for a given label is calculated in mris_anatomical_stats. Multiplying the average thickness by the area estimate I get in the output file does not give me exactly the same estimate of grey matter volume as what mris_anatomical_stats returns.

Is the mris_anatomical_stats volume estimate calculated on a vertex-by-vertex basis?

Thanks,

Alex
