Workflow tools help to shape complex analyses into efficient, reproducible programs that can be run on your local machine, on a cluster such as RMACC Summit, or even on national computing resources like the Open Science Grid (OSG). Some of these tools are container-friendly, and provide a great way to improve the reproducibility of your research. During this hands-on session we will use RMACC Summit to build workflows with two workflow tools: Snakemake and Nextflow.
