TAX CREdiT data: TAXonomic ClassifieR Evaluation Tool data repository

A standardized and extensible evaluation framework for taxonomic classifiers

This repository contains all data and Jupyter notebooks for the tax-credit project, a standardized and extensible evaluation framework for assessing short-read taxonomic classifiers.

To view static versions of the reports, start here.

Environment

This repository contains Python 3 Jupyter notebooks, but some taxonomy assignment methods (e.g., using QIIME-1 legacy methods) may require different python or software versions. Hence, we use conda parallel environments to support comparison of myriad methods in a single framework.

The first step is to install conda and install QIIME2 following the instructions provided here.

An example of how to load different environments to support other methods can be seen in the QIIME-1 taxonomy assignment notebook.

Setup and install

To clone this repository:

git clone https://github.com/caporaso-lab/tax-credit-data.git

The tax-credit python 3 package is hosted in the tax-credit-code repository.

git clone https://github.com/caporaso-lab/tax-credit-code.git
cd tax-credit-code
pip install .

OR

pip install https://github.com/caporaso-lab/tax-credit-code/archive/master.zip

To extend the 16S/ITS classification results you will need reference data sets:

wget https://unite.ut.ee/sh_files/sh_qiime_release_20.11.2016.zip
wget ftp://greengenes.microbio.me/greengenes_release/gg_13_5/gg_13_8_otus.tar.gz
unzip sh_qiime_release_20.11.2016.zip
tar -xzf gg_13_8_otus.tar.gz

Using the Jupyter Notebooks included in this repository

To view and interact with Jupyter Notebook, change into the /tax-credit-data/ipynb directory and run Jupyter Notebooks from the terminal with the command:

jupyter notebook index.ipynb

The notebooks menu should open in your browser. From the main index, you can follow the menus to browse different analyses, or use File --> Open from the notebook toolbar to access the full file tree.
