The Ki MoSys tools workflow. The workflow starts with the definition of a metabolic network (SBML model). Then this can be loaded in the network reduction tool (step 1). The output is a reduced model file. Subsequently, the user can add all the initial metabolites values that are contained in the model (step 2). The Translate kinetic equation s tool (step 3), allows to be assigned approximated kinetics (convenience, lin-log and mass-action) to the corresponding reactions in the SBML model. Add fluxes tool (step 4) use as input the new fluxes file from step 2 and set all the reference fluxes for each lin-log rate law in the reduced SBML model.
