COPASI

COPASI offers a comprehensive platform for computational systems biology, enabling users to simulate the intricate dynamics of biochemical networks. Choose between deterministic Ordinary Differential Equations (ODEs) for large population studies or the stochastic Gillespie algorithm for capturing random fluctuations in molecular interactions. Its native support for the SBML standard allows for easy sharing and validation of models across the scientific community. Additional features include steady-state analysis, metabolic control analysis, and sensitivity assessments, making it an indispensable tool for researchers aiming to understand complex biological processes.
