The group analysis for more complicated designs is the same as for thickness analysis and can be found, eg, here

It will only analyze the dat you give it (ie, bold amplitude, cvr, thickness)

Hi Doug,

I am able to get up to the mrs_glmfit step of the Surface Based Group fMRI Analysis, but it does not indicate how a comparison should be made between the two groups that I have. It only gives information on how to perform a one sample group mean test (osgm). In addition, when you mention using a mrs_glmfit-sim command, does this also generate cerebrovascular reactivity values, or does it only provide cortical thickness values? I was also hoping that I could potentially visualize an average area of low BOLD CVR for both groups. Is that possible?
