Canonically pronouced *nice*


gneiss is a compositional statistics and visualization toolbox. See [here](https://biocore.github.io/gneiss/) 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__.

# Installation

To install this package, it is recommended to use conda. An environment can installed as follows

```
conda create -n gneiss_env python=3
```

gneiss then can be installed as follows
```
source activate gneiss_env
conda install pyqt=4.11.4
pip install gneiss
```

gneiss can also be installed through conda
```
conda install -c biocore gneiss
```

To run through the tutorials, you'll need a few more packages, namely `seaborn`, `biom-format` and `h5py`.
These packages can be installed with conda as follows
```
conda install seaborn h5py
pip install biom-format
```
