cgnet's Introduction

cgnet

Coarse graining for molecular dymamics (preprint)

Dependencies

Required:

  • numpy
  • pytorch (1.2 or higher)
  • scipy

Optional:

  • mdtraj (for cgnet.molecule only)
  • pandas (for cgnet.molecule only)
  • sklearn (for testing)
  • Jupyter (for examples)
  • matplotlib (for examples)

Usage

Clone the repository:

git clone [email protected]:coarse-graining/cgnet.git

Install any missing dependencies, and then run:

cd cgnet
python setup.py install

Notes

For compatibility with pytorch==1.1, please use the pytorch-1.1 branch. This branch currently does not include the updates for variable size and Langevin dynamics, nor some normalization options.
