Figure 1

The two–sided bipartite graph. There is an edge between an miRNA and a gene if the gene is targeted by that miRNA. The quorum and error thresholds are listed below the graph. A quasi-module in this graph consists e.g. of the shaded circles (the sets T, H and V and the module edges are the thick lines). The full set of quasi-modules for this graph is found in Figure 2.
