Hello
thank you for the reply - it was very reassuring!
I have two more questions, though:
1) is that do I need to demean if I am using the -d option in randomise?
2) if I am using the Glm tool to generate the design matrix, should I
orthogonalize?
I did the analysis and almost the whole brain shows up with 0.998! So
I am wondering if I did something wrong?
Thank you so much for your advice
best wishes,
Prerona
