Hello Everyone,
I have four conditions in my task and I would like to find areas that
activation for condition A or B or C, or D. I believe this is
different from the mean (A,B,C, and D) and I can't figure out what
would be the best way to do that.
Can I do four simple contrasts [1 0 0 0], [0 1 0 0], [0 0 1 0], and
[0 0 0 1] and threshold them at some level and add them together to
get regions where A or B or C or D activated? Or is this not correct?
Thanks,
Junghee
