I don't understand. Why not use the mean thickness from FS? We have an lGI module; we have not supported it in years, but maybe it still works. https://surfer.nmr.mgh.harvard.edu/fswiki/LGI

Hi,

We were wondering what the preferred command is for extracting mean gray matter thickness/LGI

I am aware that FS outputs left/right mean thickness but wanted to be conscious of the fact that left/right hemisphere might have different sizes.
