Dear FSL experts,
i have 3 Groups with Age de-mean as a covariate and i would make the right contrasts.
Here my contrasts:
G1 G2 G3 age_D
C1 -1 0.5 0.5 0
C2 1 -0.5 -0.5 0
C3 -2 1 1 0
C4 2 -1 -1 0
C5 0 1 -1 0
C6 0 -1 1 0
C7 1 -1 0 0
C8 -1 1 0 0
C9 1 0 -1 0
C10 -1 0 1 0
I want to compare the G2 and G3 togheter versus G1. I tried to make these contrasts in C1,C2,C3,C4 but i don't know which combination is the right one.
Thank you very much for your helpfulness.
Regards
Matteo
