That call to aparcstats2table will give you the surface area. Use "-m thickness". With this, it will report whatever you passed as the -t option to mris_anatomical_stats (rh.pial_lgi in this case).

Dear FreeSurfers,
I'm facing a problem with the estimation of local gyrification index. I've already performed the analysis with QDEC and the insertion of the MEASURE1 = pial_lgi line in the .Qdecrc file, but I'd like to see if it is possible to use the /aparcstats2table /command in order to have more concise and easy-to-read results.
From the QDEC GUI I've drawn a label in the temporal pole, and applied it to all my subjects (/mris_anatomical_stats -l rh.MR_TmpPole.label -t rh.pial_lgi -b -f s1/stats/rh.MR_TmpPole.stats s1 rh/)
The problem is that when I call the /aparcstats2table --hemi rh --subjects s1 s2 ... --parc MR_TmpPole -t GI_MR_TmpPole.txt/ / / I get a .txt file like this:
rh.MR_TmpPole.arearh_rh.MR_TmpPole.label_arearh_WhiteSurfArea_area s1 6623.096171.8 s2 6257.085247.3 ...
but I'm not sure what those numbers stand for. I'm afraid they have nothing to do with the gyrification index.
Thank you,
best
elisa
