I would like to look at the connectivity within one patient group.  I tried using the one-sample button, with a design matrix of all ones and a contrast matrix of [1], with the eventual goal of adding a regressor in a design matrix. 

But I get non-signficant results for all thresholds I tried, and max size random and max size actual are both zero. 


Can I do a group mean with NBS? 
and if so, how do I set things up. 

Thanks
