Meneco

Installation

Requires Python >= 3.7

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

• Clyngor or Clyngor_with_clingo that includes the solvers

You can install Meneco by running:

python setup.py 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",
                seeds="toy/seeds.sbml",
                targets="toy/targets.sbml",
                repairnet="toy/repair.sbml",
                enumeration=False,
                json=True)

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).
