GDD-agreement between the viral PPI networks and the model networks. GDD-agreement between the viral PPI networks and the model networks. Points on the horizontal axis correspond to viral PPI networks of: EBV, HSV-1, KSHV, mCMV, and VZV herpes viruses. Lines with different labels correspond to different model networks. The vertical axis represents the average GDD-agreement between the corresponding data and model networks. For each data network, we generated 30 network model instances, each constrained to be of the size of the data. The plot reports the averaged the GDD-agreement values and standard deviations of their GDD-agreement with the data. Higher values of GDD-agreement reflect higher similarities between the networks.
