COPASI

COPASI empowers scientists to explore the dynamics of biological systems through flexible simulation approaches. Users can select deterministic ODE solvers for predictable, large-scale dynamics or employ the stochastic Gillespie method to model inherent noise and discrete events. The application's support for SBML files ensures models are portable and compatible with a wide array of databases and tools. Beyond simulation, COPASI assists with tasks like optimization and sensitivity analysis, offering a complete suite for quantitative systems biology in an accessible, standalone package.
