If you had 5.3 in addition to 4.5, you could run the following command for each subject

cd $SUBJECTS_DIR/yoursubject mri_segstats --seg mri/aseg.mgz --sum stats/aseg.53.stats --pv mri/norm.mgz --empty --brainmask mri/brainmask.mgz --brain-vol-from-seg --excludeid 0 --excl-ctxgmwm --supratent --subcortgray --in mri/norm.mgz --in-intensity-name norm --in-intensity-units MR --etiv --surf-wm-vol --surf-ctx-vol --totalgray --euler --ctab $FREESURFER_HOME/ASegStatsLUT.txt --subject yoursubject

Note that it creates stats/aseg.53.stats

Dear all,

I've been using Freesurfer v4.5.0 for some time and have reconned about 100 participants. I am wondering if there is an automatic way to obtain the total gray matter volume for all the subjects I have run so far under this version, or would it be necessary to update to v5.2?

Any help would be greatly appreciated!
