Figure 7From: SPIKE – a database, visualization and analysis tool of cellular signaling pathwaysPath finding. The user specifies the source, the target and the maximal number of edges in a path connecting them. By default, un-directed edges (that is, protein-protein interactions) are excluded from the analysis. In this example, pathways linking ATM to CASP3, a major effector of apoptosis, are sought. All paths that meet the length constraint are displayed with the shortest paths highlighted.Back to article page
