Installation

RAVEN is available as a MATLAB toolbox and as the Python package raven-toolbox. Both build the same models with the same algorithms, so pick whichever fits your workflow:

• RAVEN (MATLAB)

  Install the MATLAB toolbox — via the MATLAB Add-Ons manager, a release download, or git. Includes upgrading and removal.

• raven-toolbox (Python)

  pip install raven-toolbox, plus development installs, upgrading and removal.

Choosing a solver

Both versions need a linear-programming solver. The choice is the same for either language:

Solver	License	Good for
Gurobi	Free academic	Genome-scale models, tINIT/ftINIT, gap-filling (recommended)
GLPK	Open source	Small to medium models, getting started
SCIP	Open source	MILP problems (MATLAB)

In MATLAB, select the active solver with setRavenSolver('gurobi'). In raven-toolbox, the solver is configured through cobrapy (cobra.Configuration).
