The old Rulebase.org (of Cellucidate lineage) was shut down on October 31st, 2011. It was the first attempt at providing web services for hosting, editing, analyzing, and executing rule-based models of molecular interaction networks in the Kappa language.
While the idea remains sound and urgent as ever, our evolving understanding of rule-based modeling made it clear that a fundamental rethinking and reimplementation of the application are needed. In the meantime, we answer the need for a simple repository of models with attendant discussion threads. This should become a great place for finding biologically significant and pedagogically instructive examples of rule-based models.
Please help us improve the site with your suggestions, but for the time being we will refrain from offering computational services like simulation. To execute Kappa models, please download binaries and/or source code of simulators at KappaLanguage.org. To execute BNGL models, please visit BioNetGen.
