External Email - Use Caution
Dear FreeSurfer experts,
I try to explore the Gyrification Index of both hemispheres in a population. For this I computed the LGI using the Freesurfer pipeline and used the command suggested in previous mails:
mri_segstats --slabel subject lh $SUBJECTS_DIR/subject/label/lh.cortex --i $SUBJECTS_DIR/my_subject_id/surf/lh.pial_lgi -excluded 0 --sum lh.aparc.pial_lgi.stats
Based on:(https://secure-web.cisco.com/1_9wsKWw32_G-UJUtVnh9GwxfZh3NF5eNv2TMJEx0j2bPyq...)
With this I get one line of results for this hemisphere in this subject in the file lh.aparc.pial_lgi.stats
.... # NRows 1
# NTableCols 10
# ColHeaders Index SegId NVertices Area_mm2 StructName Mean StdDev Min Max Range
1 1 115191 82607.4 Seg0001 3.5515 0.8629 2.1340 5.9443 3.8103
I would like to clarify, which variable is reporting the gyrification index?
Thank you for your help and time.
Kind regards,
Céline Steger
