E-cyanobacterium.org is a web-based platform for public sharing, annotation, analysis, and visualisation of dynamical models and wet-lab experiments related to cyanobacteria. It allows models to be represented at different levels of abstraction — as biochemical reaction networks or ordinary differential equations. The platform is unique in providing concise mapping of mathematical models to the formalised consortium-agreed biochemical description. The main goal of the platform is to connect the world of biological knowledge with benefits of mathematical description of dynamic processes.
