Schema of the reconstruction of physical connectivity from functional dynamics. PPC is calculated for all the pairs of nodes with a common underlying physical network but different configurations of initial phases and intrinsic frequencies of oscillators. PPC for all the pairs of nodes is averaged over different initial configurations. Average WNS is built as an all-to-all connected network where each link is weighted by the average PPC between two oscillators at the ends of the links. The solid (dashed) lines denote the physical (non-physical) links which are between nodes connected (disconnected) in the physical network. The inferred network is composed of the links of the WNS whose weights are higher than a given threshold. TP denotes true predicted links (red links in both the physical and inferred networks). FP denotes non-physical links that are predicted as physical links by our method (green links in the inferred network). TN denotes true predicted non-physical links (pink dashed links in the averaged WNS). FN denotes the physical links that are predicted as non-physical links by our method (blue links in the physical network). In this example, TP = 5, TN = 5, FP = 2 and FN = 3.
