Thanks for responce, Dough.
I've looked at recon-all as you suggested, and came up with the following commandline:
mris_anatomical_stats -mgz -f lh.lgi.stats -b -a ../label/lh.aparc.annot -c ../label/lgi.annot.ctab $SUBJECT lh pial_lgi
This, however yields segfault:
INFO: assuming MGZ format for volumes. computing statistics for each annotation in ../label/lh.aparc.annot. reading volume $SUBJECT/mri/wm.mgz... reading input surface $SUBJECT/surf/lh.pial_lgi... Segmentation fault
I'm wondering whether this could be related to the fact that mris_anatomical_stats, calculates mean and stdev on the per-vertex basis over the defined label, while here we want it to calculate LGI, which is not calculated in this manner.
Thanks,
Martin

use mris_anatomical_stats. Look in recon-all to see how to invoke it. You can create another stats file (can't add it to the one that is already there).

Hi,
is it possible to obtain LGI values of cortices, similarly as curvature indices in ?h.aparc.stats? Could this value possibly be included in the ?h.aparc.stats files?
Thanks in advance,
Martin
