sourmash is published on JOSS.


The name is a riff off of Mash, combined with @ctb's love of whiskey. (Sour mash is used in making whiskey.)

Authors: C. Titus Brown (@ctb) and Luiz C. Irber, Jr (@luizirber).

sourmash is a product of the Lab for Data-Intensive Biology at the UC Davis School of Veterinary Medicine.

Installation

We currently recommend installing the 2.0 pre-release series. You can use pip to do that like so:

pip install --pre sourmash

sourmash runs under both Python 2.7.x and Python 3.5+. The base requirements are screed and ijson, together with a Rust environment (for the extension code). We suggest using rustup to install the Rust environment:

curl https://sh.rustup.rs -sSf | sh

The comparison code (sourmash compare) uses numpy, and the plotting code uses matplotlib and scipy, but most of the code is usable without these.

For search and gather you also need khmer version 2.1+.

Installation with conda

Bioconda is a channel for the conda package manager with a focus on bioinformatics software. After installing conda you will need to add the bioconda channel as well as the other channels bioconda depends on. Once you have setup bioconda, you can install sourmash by running:

$ conda create -n sourmash_env sourmash python=3.6.4
source activate sourmash_env
$ sourmash compute -h

which will install the latest alpha release.

Support

Please ask questions and files issues on Github.

Development

Development happens on github at dib-lab/sourmash.

After installation, sourmash is the main command-line entry point; run it with python -m sourmash, or do pip install -e /path/to/repo to do a developer install in a virtual environment.

The sourmash/ directory contains the library code.

Tests require py.test and can be run with make test.

Please see the developer notes for more information.
