ORGANIC

ORGANIC (Objective-Reinforced Generative Adversarial Network for Inverse-design Chemistry) is an efficient molecular generation tool, able to create molecules with desired properties. It has a user-oriented interface, and doesn't require a HPC cluster. Feel free to check our article about ORGANIC and/or contact the developers if you have any issue or are interested in collaborations.

This implementation is authored by Carlos Outeiral (carlos@outeiral.net), Benjamin Sanchez-Lengeling (beangoben@gmail.com), Gabriel Guimaraes (gabrielguimaraes@college.harvard.edu) and Alan Aspuru-Guzik (alan@aspuru.com), affiliated to Harvard University, Department of Chemistry and Chemical Biology, at the time of release.

How to use

ORGANIC has been carefully designed to be simple, while still allowing full customization of every parameter in the models. Have a look at a minimal example of our code:

model = ORGANIC('OPVs')                     # Loads a ORGANIC with name 'OPVs'
model.load_training_set('opv.smi')          # Loads the training set (molecules encoded as SMILES)
model.set_training_program(['PCE'], [50])   # Sets the training program as 50 epochs with the PCE metric
model.load_metrics()                        # Loads all the metrics
model.train()                               # Proceeds with the training
