Relation of metabolic reaction and metabolic correlation networks (pair distances). Comparison of metabolic reaction networks and metabolic correlation networks via the pairwise distances between nodes. The similarity between both types of networks (correlation network at ω = 8) has been determined for different sampling points and 0 <κ < 1. Values around zero indicate, that there is no correlation between these types of metabolic networks. The regime enclosed by the gray-shaded box describes the statistically reliable region of κ.
