Summary of the seminal network properties for the three groups of networks. The columns correspond to the following properties: threshold value for negative correlations, threshold value for positive correlations, number of nodes, number of edges, number of edges with positive weight, number of edges with negative weight, number of isolated nodes, number of connected components, the number of nodes in the largest component, the average degree, density, number of communities (determined by the greed community finding algorithm based on modularity), the modularity of the corresponding partition into communities, and the Rand index for the correspondence between the determined communities and the chemical classes for the compounds.
