COPASI is a widely used software tool for creating, simulating and analyzing models of biochemical reaction networks. It is open source free software and available for all major operating systems. Its features include deterministic and stochastic simulation, steady state analysis, stoichiometric analysis, optimization and parameter estimation, time scale analysis, sensitivities and metabolic control analysis, Lyapunov exponents, linear noise approximation, etc.
The COPASI developing team will again hold a Developer's Workshop in person. At this workshop the developers will discuss recent improvements in the software and future plans for development of the software.
