From: Predicting links between tumor samples and genes using 2-Layered graph based diffusion approach
2-Layered Network of Tumor sample and Gene. Layer 1 is the bipartite graph of Tumor samples and Genes. Layer 2 is the undirected graph of Genes. Tumor sample is represented by red node and Gene is represented by green node in the figure. The Links between Tumor sample and Gene is directed link represented by directed arrow and the links between gene is undirected link represented by line
