Dear FreeSurfer experts,

I did a group analysis in qdec, found several significant clusters and would now like to extract the mean cortical thickness of each significant cluster. I know that I have to run mri_glmfit-sim to do this, but I do not understand which commands I need to get the xxx.y.ocn.dat as output by running mri_glmfit-sim.  

Any ideas? Any help is appreciated. J

Best wishes, Julia
