Introduction

Jazzy is an efficient computational tool for the calculation of hydration free energies and hydrogen-bond acceptor and donor strengths. A publication describing the implementation, fitting, and validation of Jazzy can be found at doi.org/10.1038/s41598-023-30089-x.

If you are using Jazzy in your research, please remember to cite our publication as:

Ghiandoni, G.M., Caldeweyher, E. Fast calculation of hydrogen-bond strengths and free energy of hydration of small molecules. Sci Rep 13, 4143 (2023)

Features

• Hydration free energies
• Hydrogen-bond strengths
• Visualisation functions (SVG)
• Application programming interface
• Command-line interface

Installation via PyPI

You can install Jazzy via pip from PyPI:

$ pip install jazzy

Installation via Poetry (for development)

Requirements to install Jazzy from the code repository:

• poetry
• pyenv or conda
• python>=3.6

First check that poetry is running (v1.4.1 at March 2023)

$ poetry --version
Poetry version v1.4.1

Create a virtual environment (via pyenv or conda) and activate it. Afterwards, clone the Jazzy project from GitHub and install it using poetry.

$ git clone git@github.com:AstraZeneca/jazzy.git
$ cd jazzy
$ poetry install

If you wish to replicate our parameter fitting (see data/optuna_fitting and optimisation), you need to install the specific version of optuna. At the time of the study, we used optuna==2.3.0. You can install that manually using pip or poetry.

$ poetry install --with optuna
$ pip freeze | grep optuna
optuna==2.3.0
