What is metano?

n is an open-source software toolbox for analyzing the capabilities of metabolic networks and for assisting in metabolic reconstruction. The software is written in Python and is designed to be easy to use and run reasonably fast. n contains efficient implementations of the established computational methods flux balance analysis (FBA), minimization of metabolic adjustment (MOMA), and flux variability analysis (FVA), as well as a script for automatically analyzing all specified single- or multi-gene knockouts using MOMA or FBA, respectively. In addition, n provides several newly developed methods, including the automated plausibility checking of metabolic models and methods for the metabolite-centric analysis of flux distributions (see our publication).

All methods implemented in n are available both as Python functions and as stand-alone command line scripts, which take lists of reactions in plain ASCII format as input. n is designed to run in any Linux environment. Algorithms with a long running time have been parallelized using MPI, which allows their execution on computer clusters.

As all tools are available as stand-alone scripts that require no adjustment of numerical parameters, n is very easy to use by modelers without any programming experience.

Download metano

The current release of n is available on PyPI You can follow the Installation instructions for Linux distributions or you can run metano in a Docker container with openSUSE as guest OS.
