COPASI

COPASI delivers a comprehensive simulation suite for biochemical networks. Users can select the most appropriate mathematical framework: deterministic modeling with ordinary differential equations for large population averages, or stochastic modeling with Gillespie's algorithm for capturing inherent noise in small systems. Support for SBML files guarantees that models built in other tools can be easily imported and simulated. Additional functionalities like parameter fitting, bifurcation analysis, and generation of publication-ready plots streamline the entire workflow from model creation to result interpretation.
