Hi,

I have some question about group analysis. I have conditions of visual stimuli on the left side or the right side. I also transform all stats data to std surface. Now I want to do group analysis, but how could I flip the left and right of the data on the surf? For example, if subj A view stimuli on the left side and subj B view stimuli on the right side, is it plausible to do group analysis on subj A rh and subj B lh?

Thanks a lot!!
