Hi All,
I am having trouble modeling an omnibus F test using a repeated measure ANOVA equivalent in the GLM. I have explored this page (http://fsl.fmrib.ox.ac.uk/fsl/fslwiki/GLM) , but I'm not confident that any of these designs satisfy my design.
I have 3 different conditions (neutral, fear, sad) for 2 runs (essentially the same structure) for 2 groups of subjects (healthy, patient).
I have run my first level model (within-subject) comparing neutral, fear, and sad to implicit baseline.
I have then run a fixed effects model to combine my 2 runs.
Now I am struggling to compare all 3 conditions to essentially get an omnibus F test for the groupXcondition interaction.
Thank you in advance for any insight you can offer!
Natalie
