New release 0.7.13 (April 2017)


PySCeS CBMPy is a new platform for constraint based modelling and analysis. It has been designed using principles developed in the PySCeS simulation software project: usability, flexibility and accessibility. Its architecture is both extensible and flexible using data structures that are intuitive to the biologist (metabolites, reactions, compartments) while transparently translating these into the underlying mathematical structures used in advanced analysis (LP's, MILP's).

PySCeS CBMPy implements popular analyses such as FBA, FVA, element/charge balancing, network analysis and model editing as well as advanced methods developed specifically for the ecosystem modelling: minimal distance methods, flux minimization and input selection.

To cater for a diverse range of modelling needs PySCeS CBMPy supports user interaction via:

CBMPy fully supports a number of open community standards, SBML Level 3 Core, FBC, Groups as well as OMEX and the creation of COMBINE archives. Models can be read/written in SBML FBC versions 1 and 2 as well as older SBML leve 2 dialects.
