Hello, I would like to set up a feat analysis and I can not find an example that quite fits. I have 2 groups (12 in each group) and 3 separate scans. I have conducted inidividual first-level analyses on all 72 scans, and would like to evaluate for (a) group effect, (b) scan effect, and (c) group by scan effect. As I look at the examples, it seems I may need to have a separate EV for each person, so it seems I will have 72 rows, and columns = 24 people + 2 group EVs + 3 scan ID EVs = 29 columns. Does that seem right? I haven't figured out the group by scan interaction EVs yet. Is there a simpler way to set this up, by chance? It will be quite diffucult to manually fill in all these 0s and 1s.
Thanks so much for your help, Katie
