Online: Gather

The hackathon is being held in a virtual venue on the platform Gather. If you have never used Gather before we have a bytesize video from the March 2022 hackathon that will help you to get started.

We will create a safe list of registered participants that will be able to access the hackathon space. Make sure you register with the e-mail address you will use to access Gather.

In person: Local sites

In March 2023 we tried something new: distributed local sites. It was a massive success, with many people volunteering to organise local groups and great feedback all around. In 2024 we hope to replicate and build on that success! 🚀

If you have registered for a local site your local host will be in contact with you to outline site-specific information. For the most recent information about your site as well as the contact details of your organizer please check the event page specific to your local sites.


Even if you are attending a local site you will still join everyone online in Gather.

Please note this is not a training event. See our community foundational training event, being held March 5-6, 2024 for this purpose.


The hackathon is a great opportunity to work on any nf-core related work that you have been putting off or didn’t have time for. To help you find like-minded people or possible things to work on, we will have the following topics (formally known as groups):


For people who are new to nf-core (but not necessarily new to Nextflow) and need a bit of guidance on where to start.

Please note that attendees are expected to know the basics of working with Nextflow.

The nf-test group will focus on implementing nf-test within nf-core modules, subworkflows, and pipelines.

Suggested projects / teams:

  • Adding nf-test to existing pipelines
  • Adding nf-test to modules
  • Adding nf-test to subworkflows
  • Improving nf-test documentation and the nf-core documentation on testing

The pipelines group will focus on any pipeline-related work. This could be a DSL2 conversion of a pipeline, a new or improved feature for a pipeline, or an entirely new pipeline (please let us register a new pipeline already before the hackathon, following our guidelines). These are typically led by the main pipeline developers if they also attend the hackathon.

Suggested projects / teams:

  • Implementing nf-test within pipelines
  • Adding new functionality to existing pipelines
  • Updating pipelines to use the latest nf-core template, via template syncs
  • Teams formed around work on specific pipelines

  • Stubs for all modules
