Hi

I have a question related to calculation of the local gyrification index using FreeSurfer. I have computed the LGI and checked the results successfully.

I can get mean values of LGI for different ROI's using the command:

mri_segstats --annot my_subject_id lh aparc --i $SUBJECTS_DIR/my_subject_id/surf/lh.pial_lgi --sum lh.aparc.pial_lgi.stats But I would also like to get a single mean value of LGI for each hemisphere. Please could you advise how best to find this.

Thanks and best wishes
