Douglas, thank you very much again. So I can assume it is the lGI for the area (in this case the lobe)?

Thank you again!

The "intensity" is the mean value of the input (lh.pial_lgi in
this case) averaged over vertices. If  you wan the total number,
multiply it by the number of vertices or re-run with --accumulate.
The area is the surface area of the entire lobe.

Sorry, my mistake.

mri_segstats --annot DA011 lh lobesStrict --i
DA011/surf/lh.pial_lgi --sum lh.lobesStrict.annot.pial_lgi.stats
