Online workflow code-along: Introduction to Snakemake

Automate Your Workflow With Snakemake

Are you working with big data?

Do you need to pass your data through various software?

Oh wait! Have I updated this output file?

If you’ve ever been in this situation, you would know that it can become quite difficult to maintain consistency and accuracy.

The more manual steps we execute, the more human errors that are inevitably introduced into our analysis - hampering accuracy and reproducibility.

Sit back and let the machines do their magic.

Workflow languages automate your data analysis workflow. They also ensure that all your analysis logs are captured in an organized fashion, explicitly outline the software used, capture the input and output files at each step and even allow you to restart the pipeline from where it errored out. The process ensures higher productivity and decreases loss of resources re-running your workflow from the start. Additionally, when your data inevitably becomes big data, workflow languages allow you to easily scale up - meaning, you can move your analysis to a high performance cluster (HPC) without stress!

In this hands-on workshop, ESR’s Leah Kemp and the NeSI team will guide you through an introduction to Snakemake, a workflow language with its basis in the popular programming language, Python. Attendees can expect to learn:

Who should attend

This Workshop is intended for anyone who has several steps in their data analysis workflow. It is a hands-on workshop, meaning you will be coding along with Leah and the NeSI team.
