Hi everyone,
I have been trying to test a mixed-model factorial design in SPM5 with
no success. A few others from the list have recently posted similar
questions, we have been in touch, but none of us has found a solution.
What we do know is that we need to model subjects in a flexible
factorial. We are able to test the within-subjects factor but the
contrast manager won't let us test the between-subjects factor (we are
told that the contrasts are invalid, even though they sum to 0).
Does anyone know why this might be happening or what we can do to solve
the problem? I've honestly tried everything I can think of.
Thanks a lot,
Nick Rule
