Hackathon projects

Work within the hackathon will be loosely gathered into projects. More details to come, but so far our idea is to work in the following areas:

  • DSL2 / modules
    • DSL2 pipeline conversion (specific pipelines)
    • Writing modules for specific tools
    • DSL2 module code linting and tests
    • DSL2 module template
  • Contribute to a pipeline
    • Syncing nf-core template to pipelines
    • Work on specific pipelines (e.g. sarek, scrna)
  • Framework tools
    • Sample sheet standardisation (helper tools / website launch / PEP)
    • RefGenie
  • Documentation
    • Configs
    • Website docs overhaul
