VIBRAtional AVeraging (vibrav)

A tool to perform vibrational averaging of molecular properties on molecules.

Installation

To use this code package you must download the development version and execute

pip intsall -r requirements.txt -e .

and to build the documantation

pip install -r requirements.publish.txt -r requirements.txt -e .

Building the documentation

The docs are built with the sphinx-apidoc module. It will generate .txt files with the contents of the docstrings in the python code. We use the sphinx_bootstrap_theme for our documentation. To install it run pip install sphinx_bootstrap_theme.

To build the documentation,

cd docs/
make html

To view the built documentation (assuming already in docs directory),

cd build/html
xdg-open index.html

Or, on the Windows Subsystem Linux,

cd build/html
cmd.exe /C start index.html

Requirements

• numpy
• pandas
• numba
• exatomic
