The ViewCommonPaths program helps to simultaneously visualize a set of numeric sequences that have the same start and end elements by drawing them into a common directed acyclic graph (DAG). In particular, ViewCommonPaths helps to simultaneously visualize a set of allosteric communication paths with the same start and end residues. Given a set of allosteric paths (each a sequence of residues), ViewCommonPaths creates a DAG from the set of individual pathways and allows a quick visual analysis of these pathways and the relationships among the residues along these paths.
