gneiss is a compositional data analysis and visualization toolbox designed for analyzing high dimensional proportions. See here for API documentation.

Note that gneiss is not compatible with python 2, and is compatible with Python 3.4 or later. gneiss is currently in alpha. We are actively developing it, and backward-incompatible interface changes may arise.


To install this package, it is recommended to use conda. First make sure that the appropriate channels are configured.

conda config --add channels https://conda.anaconda.org/bioconda
