It is not the same. You would have to weight by the number of vertices. You can also run mris_anatomical_stats passing the ?h.cortex.label as the label and the lgi overlay as the input

Freesurfer Support,
I have seen previous message threads on extracting LGI measurements across ROIs, however I have yet to find anything which would provide a summary LGI across an entire hemsphere. Other measurements like cortical thickness have a measurement like this. Is there a measurement like this for LGI?
If I take the mean of all of the ROIs would that be equivalent to a hemispheric LGI measure?
Thanks!
