Dear experts,
All of my subjects have 4 fMRI scans (different pharmacological conditions). I've created my contrast of interest for each subject and condition at the first level. Now I want to use the 1-way ANOVA within subject model at the 2nd level.
Can you please tell me if the attached design matrix looks ok?
Before I can perform t tests, I suppose I need to define a F contrast to test for a main effect of condition. Can you please help me how this F contrast should look like? Or in general, how do I need to define the contrast in this ANOVA model?
Many thanks for your help, much appreciated.
Best wishes
Andre
