Fig. 4From: Qualitative dynamics semantics for SBGN process descriptionStories of an SBGN-PD map. Top: The SBGN-PD map of Fig. 3. Bottom: the set of possible (non-singleton) stories respecting constraints (i-iv) and the maximally valid sets of stories. Final sets are colored in blue, and epn-maximal sets are colored in green. Each of the constants a, b, c, adp and atp denotes the EPN whose label equals that constant. Constant aP denotes the phosphorylated macromolecule labeled “a”Back to article page
