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.area rh_rh.MR_TmpPole.label_area rh_WhiteSurfArea_area
s1                  6623.0 96171.8
s2                  6257.0 85247.3
...

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
