Metabolic Network Completion. Compute minimal completions to your draft network with reactions from a repair network.

Project description

Meneco PyPI version


Requires Python >= 3.7

Required packages (starting from version 2.0 of the package):

You can install Meneco by running:

python install

You should always use a virtual environment (virtualenv, virtualenv wrapper) when using Python

Usage from console

Typical usage is:

meneco -d draftnetwork.sbml -s seeds.sbml -t targets.sbml -r repairnetwork.sbml

For more options you can ask for help as follows:

usage: meneco [-h] -d DRAFTNET -s SEEDS -t TARGETS [-r REPAIRNET]
                   [--enumerate] [--json]

optional arguments:
  -h, --help            show this help message and exit
  -d DRAFTNET, --draftnet DRAFTNET
                        metabolic network in SBML format
  -s SEEDS, --seeds SEEDS
                        seeds in SBML format
  -t TARGETS, --targets TARGETS
                        targets in SBML format
  -r REPAIRNET, --repairnet REPAIRNET
                        perform network completion using REPAIRNET a metabolic
                        network in SBML format
  --enumerate           enumerate all minimal completions
  --json                produce JSON output

Calling Meneco from a python script

You can use Meneco from python by calling the command run_meneco() with the paths of files as input arguments and a boolean value for the enumeration (True for the enumeration, else False) :

from meneco import run_meneco

result = run_meneco(draftnet="toy/draft.sbml",

The output will be the set of unproducible targets, reconstructable targets, a dictionnary of essentials reactions for each target, one minimal solution, the set of reactions belonging to the intersection of solutions, the set of reactions belonging to the union of solutions and a list of lists corresponding to the reactions for each solution (if enumeration == True).

For a step by step demonstration on how to use Meneco as a library, have a look at our notebooks here or here.

The concepts underlying Meneco is described in this paper:

T. Schaub and S. Thiele, “Metabolic network expansion with answer set programming,” in Lecture Notes in Computer Science (including subseries Lecture Notes in Artificial Intelligence and Lecture Notes in Bioinformatics), 2009, vol. 5649 LNCS, pp. 312–326.

A first application of the method was presented in:

G. Collet et al., “Extending the Metabolic Network of Ectocarpus Siliculosus Using Answer Set Programming,” in LPNMR 2013: Logic Programming and Nonmonotonic Reasoning, 2013, pp. 245–256.


Sample files for the reconstruction of Ectocarpus are available here: ectocyc.sbml, metacyc_16-5.sbml, seeds.sbml, targets.sbml
