Hi Alan, lGI is different from the folding index. lGI is not yet extracted automatically in the different regions, because it's more meant to be use at the vertexwise level. But you can easily obtain the lGI values averaged over the Desikan's ROI using the following command:
mris_anatomical_stats -a SUBJ/label/?h.aparc.annot -t SUBJ/surf/?h.pial_lgi -f SUBJ/stats/lh.aparc_lgi.stats SUBJ ?h Please note than then you will get the average lGI values for each region for each subject under the thickness column, and that the volume in this same text file will not mean anything relevant anymore. Then you can go for: aparcstats2table --subjects ALL_YOUR_SUBJECTS --hemi ?h --meas thickness --parc aparc_lgi --tablefile aparc_lgi_?h.txt Let me know if you have difficulties, Marie On Sep 3, 2013, at 1:53 PM, Alan Francis <alandarkene...@gmail.com> wrote: > Hi Marie et al, > > I have run recon all on the data and calculated LGI for all the brains in my > dataset.
