Dear Alfonso or CONN experts,
Running R2R I got this message below.

I understand that it is because I set only left caudate for the R2R analysis, which would actually be a seed based analysis. Is it possible to build this seed based with the same type of graph CONN offers for R2R analysis? 

Thanks a lot all best

Renzo
