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.

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

Sorry, to be clear, there is a measurement for bilateral mean thickness offered by default? I'm able to gather the left mean thickness and the right mean thickness easily.

why not just average them together? Or are you hoping that FS provides this last small step? I don't think that we do ...
