Dear Alfonso

thank you for your great toolbox!

I have a question regarding semipartial correlation and circularity. I have entered several networks derived from ICA in seperate seed-to-voxel analyses using bivariate correlation. 2nd level results showed, among others, positive connectivity of those networks to the thalamus. After these results were obtained, analyses were re-run, this time using semipartial correlation and entering the thalamus as a variable to control for.
However, it appeared to me that this analysis is circular and somehow trivial. Is this really the case? I can't still wrap my head around it.

Thank you very much in advance!
