Two main strategies : "pure" overlap of compounds or input/output (only sources and sinks, create directed network)
Genome-scale metabolic networks are often partitioned into metabolic pathways. Pathways are frequently considered independently despite frequent coupling in their activity due to shared metabolites. In order to decipher the interconnections linking overlapping pathways, this app proposes the creation of "Pathway Network", where two pathways are linked if they share compounds.
