Hi, I’m using TDT toolbox to analyze my results. I’m totally new to MVPA, so it may be a silly question.
I have learned that I can get a contrast result by setting the label into 1 and -1 for two regressors, but what I really want is to get the contrast result of two contrasts. For example, I want to know (regressor 1 - 2)-(regressor 3 - 4). I can just define contrast (1 -1 -1 1) in SPM, but what should I do in TDT?
Thank you very much. Looking forward to your reply.
