StochSS: Stochastic Simulation Service. StochSS is an integrated development environment (IDE) for simulation of biochemical networks: Define models in an easy-to-use model editor. Interactive 3D visualization of models and results. Scale your simulations to the cloud with a click-of-a-button. StochSS automatically converts your models from ODE, to well-mixed stochastic, to spatial stochastic. Supports parameter estimation and parameter sensitivity. Supports parameter sweeps. Multi-user environment makes collaborations easier.
