Hi Hongyu,

No, all you need to do is to switch the group-level contrast from +1s to -1s!

w run, right? What should I do for the
higher analysis, group analysis? Same as the original one? I am not sure about
it. Maybe I need to set a different contrast for deactivation group analysis?

I appreciate your response.
