No future instance of this course is planned yet


Data analyses usually entail the application of many command line tools or scripts to transform, filter, aggregate or plot data and results. With ever increasing amounts of data being collected in science, reproducible and scalable automatic workflow management becomes increasingly important. Snakemake is a workflow management system, consisting of a text-based workflow specification language and a scalable execution environment, that allows the parallelized execution of workflows on workstations, compute servers and clusters without modification of the workflow definition. Thereby, a scheduling algorithm based on a multidimensional knapsack problem allows Snakemake to maximize workflow execution speed while not exceeding given constraints like the number of available processor cores, cluster nodes or auxilliary hardware like graphics cards.

Since its publication, Snakemake has been widely adopted and was used to build analysis workflows for a variety of high impact publications. With about 5000 homepage visits per month, it has a large and stable user community.


This course is addressed to bioinformaticians and life scientists interested in learning how to create workflows of data management.

Learning outcomes

This course will introduce the Snakemake workflow definition language. After completing this course, the participants should be able to:

  • use the Snakemake execution environment to scale workflows to compute servers and clusters while adapting to hardware specific constraints.
  • create reproducible analyses that can be adapted to new data with little effort.


Knowledge / competencies

Participants should have basic programming skills in Python. You can test your skills in the quiz in this link.


Participants are required to have a laptop with a command line terminal installed.


The registration fees for academics are 60 CHF and 300 CHF for for-profit companies.

You will be informed by email of your registration confirmation. Upon reception of the confirmation email, participants will be asked to confirm attendance by paying the fees within 5 days.
