Hello experts,
I wold like to ask for advice on setting up an analysis.
I have a 2x2 experimental design with two unbalanced groups fMRI data.
The questions are -
(1) in the control group, which areas are associated with factor A, factor B, and factor A*B, and
(2) In the regions identified from Q1, does the measure in the experimental group differ from the control group for factor A, factor B, and factor A*B .
I would like to add the covariates age, sex, and head motion to this model.
So, the 2 factors are within subject variables, and the groups and covariates are between subject factors. From what I understood from the handouts and threads here, I should use 3dMVM or 3dLME. I also saw one where Gang has suggested to use a 3dttest++ instead for each comparison directly.
I would appreciate you advice. Thanks a lot!
-S
