COPASI is a software application for modeling and simulation of biochemical networks. The software package has a GUI that lets users define biochemical network models by entering chemical reactions and kinetic equations. A powerful simulation engine can then perform simulations of the dynamics of the networks and carry out many different computational analyses. COPASI can simulate dynamics using either an ODE approach or a stochastic chemical kinetics approach (Gillespie-type algorithms).License: Free for non-commercial useChanges:
A severe problem in the SBML export, which lead to invalid SBML files due to duplicate use of the same SLD, has been fixed.
