Getting started

To run this project, simply git clone the repository and type python __main__.py in the terminal:

$ python __main__.py

Developing a Predictive Model

See models.py for examples of how to create your own model.

Using a Predictive Model

See prediction.py for examples of how to use pre-trained models.

Memory Usage

OpenProtein includes a preprocessing tool (preprocessing.py) which will transform the standard ProteinNet format into a hdf5 file and save it in data/preprocessed/. This is done in a memory-efficient way (line-by-line).

The OpenProtein PyTorch data loader is memory optimized too - when reading the hdf5 file it will only load the samples needed for each minibatch into memory.
