Comparing contextual network for GRNs defining cell cycle M-phase and S-phase (Table 1 ). Each point is an interaction from the two contextual networks, colored by the target gene functional annotation. X and Y axis are xi^2 of the S-phase and M-phase networks. GRN interactions targeting S-phase genes (purple) have higher ERV in the S-phase contextual network, and interactions targeting M-phase genes (green) have higher ERV in the M-phase contextual network
