Abstract Background Modeling of molecular networks is necessary to understand their dynamical properties. While a wealth of information on molecular connectivity is available there are still relatively few data regarding the precise stoichiometry and kinetics of the biochemical reactions underlying most molecular networks. This imbalance has limited the development of dynamical models of biological networks to a small number of well-characterized systems. To overcome this problem we wanted to develop a methodology that would systematically create dynamical models of regulatory networks where the flow of information is known but the biochemical reactions are not. There are already diverse methodologies for modeling regulatory networks but we aimed to create a method that could be completely standardized . independent of the network under study so as to use it systematically. Results We developed a set of equations that can be used to translate the graph of any regulatory network into a continuous dynamical system.
