Design matrix for the group analysis showing the dopamine odor conditioning interaction (D1), control drug conditioning interaction (GF), and the orthogonalized place preference score (BH). Each row corresponds to a subject. The gray scale to the right represents the regressor values. The +1 or −1 represents white or black color the subject was cocaine-conditioned to almond or rose. The table below shows the statistical contrasts defined as a function of these regressors. This is standard output from the FSL fMRI analysis program.
