Dear Vladimir,

I used 0.05 FWE.

Thanks,

Alexandra

Dear Alexandra,

Do you mean 0.05 FWE, or 0.05 uncorrected?

I have done a repeated measures ANOVA using T-contrasts with weights [1 -1] and [-1 1] and an F-contrast with a weight matrix [eye(2) ones(2,54)/54]. I kept the threshold at 0.05. There were no significant clusters in either of the T contrasts, but several in the F-contrast. I'm having trouble understanding how this can be.
