They ride with what I refer to as the four horsemen of the reproducibility apocalypse:
  1. Publication bias
  2. Low statistical power
  3. P-value hacking
  4. HARKing (hypothesizing after results are known)

What is needed for a Workflow Run RO-Crate?

  • Workflow language & version

  • Workflow engine & version (e.g. Toil)

  • Workflow definition

  • Input data (or pointers to such)

  • Parameters? What can be implicit and explicit? (see BCO?)

  • Tool Dependencies to install (mostly implied by CWL/Nextflow/Galaxy, but might need versions/repos)

  • Container platform requirement [e.g. Docker, Conda]

  • Operating system requirement

  • Hardware requirements (memory, CPU, GPU)

    • Equivalent of AWS cloud instance type sufficient?

  • Where to run/submit (e.g. usegalaxy.eu)

  • Explicit/resolved container IDs

  • Archive containers from Docker Hub (protect against image expiration)

  • ...
