Two questions:

1) Does the order of the output indicate a ranking from "strongest" to "weakest" connectivity?

2) Is there any way to actually get an r value?

Thanks!

Amy

Hi Amy:
As you konw, all is in the GLM framwork.To do correlation analysis, you can
try 'Basic models' ---> 'simple regression' in SPM.
