Documentation

Install

All dependencies are installed via conda using the bioconda channel. The workflow and some dependencies require Python 3.

The intended usage requires conda.

Further dependencies will be installed on the first execution of the assembly or annotation protocol and re-used on subsequent executions of the protocols.

For more information related to bioconda, see: https://bioconda.github.io/

As a New Environment

With conda, execute:

conda create -n atlas -c bioconda -c conda-forge python>=3.6 snakemake pandas bbmap=37.78 click ruamel.yaml biopython

Load the environment:

source activate atlas

Install atlas:

pip install -U metagenome-atlas

or install the up to date atlas from github:

git clone https://github.com/metagenome-atlas/atlas.git
cd atlas
pip install .

Getting Started

After installing, one needs to download the required databases and create a sample configuration file.

Databases

To download the databases and their respective metadata databases:

atlas download -o ~/databases

The downloads use approximately 100 GB of disk space.

Configuration File

To create a configuration file run:

atlas make-config --database-dir ~/databases config.yaml ~/directory_with_fastqs

Sample names and file paths along with default settings will populate config.yaml. This YAML file can be updated with any text editor.

Sample names should be A-Z characters and can be dash ("-") delimited.

For complete documentation, please see:

Assembly

After editing your configuration file and adjusting any additional parameters we run assemblies across our samples using:

atlas assemble config.yaml

By default, this will write results into our current working directory across the total number of CPU cores available.
