Before revision:  Here we present a method for the  comparison of an unlimited number of networks: Co-expression Differential Network Analysis (CoDiNA) . Our method distinguishes between links that are common to all networks, links that are specific to only one of the compared networks, and links that are different in that their sign changes between networks.
After revision:  Here we present a method for the comparison of an unlimited number of networks: Co-expression Differential Network Analysis (CoDiNA) for detecting links and nodes that are common to all networks, links that are specific to only one of the compared networks, and links that are different in that their sign changes between networks.
