Are there instructions for how to do volume functional analysis and how to do it that way? I've only ever done surface based analysis.

Hi Katie,

you could do it in the volume, but I doubt there's any way to do it on the surface.

 Hi all,

I was wondering if anyone had any idea if it was possible to combine together ROIs from the separate hemispheres into one ROI (for example LH V1 and RH V1) and then perform a functional ROI analysis on it. I know how to combine ROIs (through labels_union) and how to do a functional ROI analysis (using func2roi-sess and roisummary-sess), but I don't know if it is possible to do it with a label that runs across both hemispheres. Thoughts?

Thanks, Katie

No errors, I hadn't actually tried it because everything else was so hemispheric based, and I didn't want to just blindly try it and be unsure of the data I got out. So I should be able to (in surface space) draw a LH and RH ROI, combine them using labels_union and do an standard ROI analysis on that?

Hi Katie, it should not matter that they are across hemispheres. Are you getting an error? doug
