Dear FS users,

can anybody help me in understanding the results of the localGI pipeline?
After calling the

recon-all -s subj -localGI

recon-all -s subj -qcache -measure pial_lgi


mri_segstats --annot subj lh aparc --i $SUBJECTS_DIR/subj/surf/lh.pial_lgi --sum lh.aparc.pial_lgi.stats


what I obtain is a text file with 10 columns, i.e.

# TableCol  1 ColHeader Index 
# TableCol  2 ColHeader SegId 
# TableCol  3 ColHeader NVertices 
# TableCol  4 ColHeader Area_mm2
# TableCol  5 ColHeader StructName
# TableCol  6 ColHeader Mean 
# TableCol  7 ColHeader StdDev
# TableCol  8 ColHeader Min
# TableCol  9 ColHeader Max
# TableCol 10 ColHeader Range

and 34 rows (i.e. 34 ROIs).

What I cannot understand is the meaning of the last five columns (intensity mean, stdev, min, max, range). Is this "intensity" measure linked to the gyrification index? If yes, how? And, if no, how can I obtain the actual gyrification index?

Thank you.

Best,
Elisa
