By default, mri_glmfit-sim will compute a spatial average inside of a cluster to create the OCN table, so the values do not agree with the table below. In he case of area or volume inputs, it needs to compute the sum instead of the average. I have just modified this program to do this. I've attached this new version. Copy it to $FREESURFER/bin To run, add --spatial-sum to the command line

To make it clear, I would like to extract the area of each subject in the cluster. May I know if this is the correct way? If not, it’s appreciated if you would point it out. Thanks!

Dear Freesurfer Experts,
As I’d like to extract the average value of each subject in the cluster after running group analysis, may I know the unit of these numbers?
Since the one I’m running is surface area, and the cluster is 444mm^2, all the numbers in the file cache.th40.neg.y.ocn.dat is in the range of [0.55 1.05], may I know if this is correct and if so, how the unit is for those? Thanks a lot!
