Hi gurus,

Is it possible to get sub-brick output for the main effect of a covariate included in 3dttest++? For example, if I run a test with data from setA and setB, and include age in a covariate file, I currently get the group effect and the group by age interaction. I would also like to look at the age effect alone. I'm trying to avoid using 3dRegAna because I don't want to re-center variables each time I add a subject.

Thanks
