Hello, I have a general question regarding the difference between contrasts and f-tests in completing a repeated measures 2 (2 groups) by 2 (factors) ANOVA with FEAT. I coded group in the evs and set up contrasts to look for directional differences by using -1 and +1 and also created a contrast for the group means separately and put them into an F test. In the output there are no areas of activation for one of the groups and no areas of activation for either of the directional tests but there are several areas of activation for the f test. Are f tests thresholded differently than contrasts? How does the one image show you main effects and the interaction? I hope this makes sense. Thanks! Rachel Force
