Dear SPM Experts,
I am running a 3 x 2 repeated measures ANOVA with a flexible factorial design.
My design is Group (3) x Conditions (2), with 69 subjects.
My column order is Sx G1 G2 G3 C1 C2 G1C1 G1C2 G2C1 G2C2 G3G1 G3C2.
I get confused when it comes to define the contrast for main effect of conditions.
I tried [zeros (1, 69) 0 0 0 1 -1 0 0 0 0 0 0] and [zeros (1, 69) 0 0 0 0 0 1 -1 1 -1 1 -1].
Neither of them is working.
Could you tell me what I am doing wrong and what would be the correct contrast to see the main effect of conditions?
Thank you very much
Best regards
Caroline
