Dear Freesurfer developers, I would like to run Local Gyrification Index analysis for a group of healthy controls and a single patient. After running recon-all -s <subj> -localGI command, we get lh.pial_lgi and rh.pial_lgi surf files. In the last stage of this analysis, local gyrification index values are calculated at each pial vertices.
In the wiki, it is said that the next process should be done in qdec, but since I have only one patient, GLM analysis would not be suitable. Thus, I would like to get the LGI values of each subject as e.g. text files (like stats files for curvature, thickness, gm volume), and use them for my own analysis (not in qdec). I know that we can get parcel-wise anaysis values using this command: mri_segstats --annot CASE lh aparc \ --i $SUBJECTS_DIR/CASE/surf/lh.pial_lgi \ --sum lh.aparc.pial_lgi.stats But I would like to use vertex-wise analysis values for my won analysis. Is it possible? Can I learn the command I need to use to get these values for each subject? Thank you, Buse -- Buse Urgen
