MDGO

PyPI - Downloads

Codacy Badge

docs Linting Test

An all-in-one code base for the classical molecualr dynamics (MD) simulation setup and results analysis.

1. Installation

1.1 Installing from PyPI

To install the latest release version of mdgo:

pip install mdgo

1.2 Installing from source code

Mdgo requires numpy, pandas, matplotlib, scipy, tqdm, statsmodels, pymatgen>=2022.0.9, pubchempy, selenium, MDAnalysis (version 2.0.0-dev0 prefered) and their dependencies.

Getting Source Code

If not available already, use the following steps.

  1. Install git, if not already packaged with your system.

  2. Download the mdgo source code using the command:

    git clone https://github.com/htz1992213/mdgo.git

Installation

  1. Navigate to mdgo root directory:

    cd mdgo

  2. Install the code, using the command:

    pip install .

  3. The latest version MDAnalysis==2.0.0.dev0 is recommended, you may download the source code of the latest MDAnalysis from github and install using pip to replace an existing version.

Installation in development mode

  1. Navigate to mdgo root directory:

    cd mdgo

  2. Install the code in "editable" mode, using the command::

    pip install -e .

  3. The latest version MDAnalysis==2.0.0.dev0 is recommended, you may download the source code of the latest MDAnalysis from github and install using pip to replace an existing version.
