Visualization of subnetworks inferred from the coexisting ecotypes data set. The visualization was created by merging separately inferred subnetworks resulting from a parameter sweep of the edge cost from 0.025 to 0.975. The width of the edges represents the maximal 30 mutation cost for which these edges were selected. The width of the edge displays the stringency at with the edge was selected (the wider the edge the more stringent the condition. More Stringent conditions correspond to higher edge costs). Node borders are subdivided into two parts to visualize in which strain a mutation occurred. The inner color of the nodes represents the degree of differential expression (L ecotype compared with S ecotype). The colors of the edges represent the edge types.
