What is COBRApy?

COBRA methods are widely used for genome-scale modeling of metabolic networks in both prokaryotes and eukaryotes. COBRApy is a constraint-based modeling package that is designed to accommodate the biological complexity of the next generation of COBRA models and provides access to commonly used COBRA methods, such as flux balance analysis, flux variability analysis, and gene deletion analyses.

Our aim with COBRApy is to provide useful, efficient infrastructure for:

  • creating and managing metabolic models
  • accessing popular solvers
  • analyzing models with methods such as FVA, FBA, pFBA, MOMA etc.
  • inspecting models and drawing conclusions on gene essentiality, testing consequences of knock-outs etc.

Our goal with COBRApy is for it to be useful on its own, and for it to be the natural choice of infrastructure for developers that want to build new COBRA related python packages for e.g. visualization, strain-design and data driven analysis. By re-using the same classes and design principles, we can make new methods both easier to implement and easier to use, thereby bringing the power of COBRA to more researchers.

The documentation is browseable online at readthedocs <https://cobrapy.readthedocs.org/en/stable/>_ and can also be downloaded <https://readthedocs.org/projects/cobrapy/downloads/>_.

Installation

Use pip to install COBRApy from PyPI <https://pypi.org/project/cobra/>_ (we recommend doing this inside a virtual environment <http://docs.python-guide.org/en/latest/dev/virtualenvs/>_)::

pip install cobra

If you want to load MATLAB models, you will need additional dependencies. Please install::

pip install cobra[array]

For further information, please follow the detailed installation instructions <INSTALL.rst>_.
