• conda install -c conda-forge rdkit
• conda install pyqt matplotlib pytorch pexpect tensorflow
• pip install molsets

Usage

Run the application with python app.py

Otimization

In the optimize tab you can select the number and the descriptors to optimize setting the miniumum and maximum value. Opt field can be used, selecting the Similarity and UserFragment descriptor, in order to specify the SMILES of the reference molecule or fragment respectively.

Generation

In the generate tab you can use the optimized model to generate a molecular library. First select the desired .ckpt file of the generative model obtained in the Optimization stage.
