Dear Freesurfer Experts,

When in the process of analyzing grey matter volumes, I have found that the totals from the summing of the lh.aparc.stats and rh.aparc.stats do not match with the total grey matter volume found from the mris_anatmoical_stats command.

Does anyone know which value is more accurate in terms of grey matter volume?

Thanks,
