Hi
Thanks for the reply. Just to make sure....
Please see this model again.
http://fsl.fmrib.ox.ac.uk/fsl/fslwiki/GLM#ANOVA:_2-groups.2C_2-levels_per_subject_.282-way_Mixed_Effect_ANOVA.29
Suppose there are 4 people with first 2 people in group 1 and the last 2 people in group 2.
EV1 is originally -1 1 -1 1
EV2 is originally -1 1 1 -1 (*Question: so I just multiply the last 2 people with -1 ? )
And now I should do......(*Question: please check if that's okay)
EV1 -0.5 0.5 0 0
EV2 0 0 -0.5 0
EV3 -0.5 0.5 0 0
EV4 0 0 0.5 -0.5
Thanks so much!
