Requirements

SyGMa requires RDKit with INCHI support

Installation

• Install with Anaconda: conda install -c 3d-e-Chem -c rdkit sygma

OR

• Install RDKit following the instructions in http://www.rdkit.org/docs/Install.html

AND

• pip install sygma OR, after downloading sygma, python setup.py install

Example: generating metabolites of phenol

import sygma
from rdkit import Chem

# Each step in a scenario lists the ruleset and the number of reaction cycles to be applied
scenario = sygma.Scenario([
    [sygma.ruleset['phase1'], 1],
    [sygma.ruleset['phase2'], 1]])

# An rdkit molecule, optionally with 2D coordinates, is required as parent molecule
parent = Chem.MolFromSmiles("c1ccccc1O")

metabolic_tree = scenario.run(parent)
metabolic_tree.calc_scores()

print metabolic_tree.to_smiles()

Docker

SyGMa can be executed in a Docker (https://www.docker.com/) container as follows:

docker run 3dechem/sygma c1ccccc1O
