Hi,
I am looking for a matrice to use to obtain resting-state fMRI contrast map for 3 factors and 1 level. I have 3 groups (group A, group B and group C), with each subjects having only one scan. I would like to have those contrast : A<B, A>B, A<C, A>C, B<C, B>C.
I found a matrice, but I believe this one has those contrasts: A>B+C, B>A+C, C>A+B. I feel like what I want is like the "post-hoc part" of those contrasts.
Do you have any suggestion to help me set up this model?
Thank you in advance
Alexandra
