Hi,
I am trying to design a GLM matrix to analyze t1 images from a group of 40 subjects and I don't find examples in the randomise or FEAT user guides that fits my wanted design. Here are the details of my subjects:
40 total subjects, divided into 2 groups (Treatment: Drug = 19 and Placebo = 21) and each groups are sub divided in 2 more groups (Response: for Drug: 8 responders and 11 non-responders, for Placebo: 11 responders and 10 non-responders).
I have scans from 2 different time for all the subjects and I want to compared longitudinally.
How can I built a matrix that will compare : 1.drug vs placebo, 2. Responders vs Non-responders, and finally the interaction between drug and response.
Thanks you!
