Hi Ritobrato,
Nick already answered your query. Just a small add: the gold standard to use local gyrification index is to compute vertex-wise analyses rather than parcel-wise comparisons. Indeed, lGI at each point already quantifies the gyrification in the surrounding region. As a result, the average lGI in a given cortical region will also reflect to some (minimal) extent the gyrification in the neighboring gyral regions.
Hope it helps,
Marie

this command can be used:
mri_segstats --annot my_subject_id lh aparc \ --i $SUBJECTS_DIR/my_subject_id/surf/lh.pial_lgi \ --sum lh.aparc.pial_lgi.stats
i've updated the lGI wiki page to include this as well.

Hi All,
I have run
recon-all -s <subj> -localGI
Now I want to get the gyrification Index of a particular label. Is there a way to do that ?
Please let me know
Thanks
Ri
