Dear SPM expert,
I need to test the interaction between my fMRI data and two scalar variables. Since I want to explore also the interaction between the clinical scores, I'm thinking about setting an ANOVA test. Is this the right choice? If it is, how is it best to proceed setting the factors and cells of ANOVA test? Is there any practical tutorial out there on the internet? (I looked around for some while but I was unable to find any simple information, for "dummies").
Thanks in advance
Chiara
