Dear FreeSurfer Experts,

I would like to extract the mean thickness for each subject, and I can see that in the lh.aparc.stats, there are three lines. For example:

# Measure Cortex, NumVert, Number of Vertices, 107414, unitless
# Measure Cortex, WhiteSurfArea, White Surface Total Area, 73280.4, mm^2
# Measure Cortex, MeanThickness, Mean Thickness, 2.56763, mm

I am wondering what command I can run with aparcstats2table or mris_calc to retrieve these three pieces of information for each subject?

And is the MeanThickness across the whole brain supposed to be (lh + rh)/2?

Best,
Daniel
