ChemGAN challenge

• Code for the paper: Benhenda, M. 2017. ChemGAN challenge for drug discovery: can AI reproduce natural chemical diversity? arXiv preprint arXiv:1708.08227.

• Chat room: https://gitter.im/Startcrowd/drugdiscovery

• Requirements: Rdkit version 2017.03.3 from Anaconda, Tensorflow 1.0.1

• The code has not been cleaned, don't hesitate to post an issue if you don't find what you are looking for.

• To make the DRD2 case work, take clf.pkl here, rename it clf_drd2.pkl, and put it in the appropriate folder. It's the SVM activity model of DRD2 by Marcus Olivecrona.

• To make the QED case work, you need Silicos-it.

• In order to train the model, cd into model and run

python train_ogan.py exp.json

where exp.json is a experiment configuration file.

• This code is otherwise based on ORGAN. Many thanks to the ORGAN team.
