Tool family 🏠

pySBML is part of a larger family of tools that are designed with a similar set of abstractions. Check them out!

• MxlPy is a Python package for mechanistic learning (Mxl)
• MxlBricks is built on top of MxlPy to build mechanistic models composed of pre-defined reactions (bricks)
• MxlModels supplies flat, single-file versions of MxlBricks models for easy inspection
• MxlWeb brings simulation of mechanistic models to the browser!
• Parameteriser looks up kinetic parameters from BRENDA and other databases
