Hello -

I am doing analysis on the surface and would like to extract the mean time-series from a bilateral ROI. My surface data and ROIs are divided by hemisphere, but I would only like one mean time-series in the end. I can think of a few convoluted ways to go about this, but is there a quick way extract the mean of a ROI from both hemis in one step?

Thanks,

Dustin
