The umi_tools dedup command is not currently deterministic, even if --random-seed is set, unless the PYTHONHASHSEED environment variable is also set. Detailed in CGATOxford/UMI-tools#440 and https://github.com/CGATOxford/UMI-tools/pull/470. Not fixed in the main umitools, so just explicitly export the environment variable here.

  • This comment contains a description of changes (with reason).
  • If you've fixed a bug or added code that should be tested, add tests!
  • If you've added a new tool - have you followed the module conventions in the contribution docs
  • If necessary, include test data in your PR.
  • Remove all TODO statements.
  • Emit the versions.yml file.
  • Follow the naming conventions.
  • Follow the parameters requirements.
  • Follow the input/output options guidelines.
  • Add a resource label
  • Use BioConda and BioContainers if possible to fulfil software requirements.
  • Ensure that the test works with either Docker / Singularity. Conda CI tests can be quite flaky:
    • PROFILE=docker pytest --tag <MODULE> --symlink --keep-workflow-wd --git-aware
    • PROFILE=singularity pytest --tag <MODULE> --symlink --keep-workflow-wd --git-aware
    • PROFILE=conda pytest --tag <MODULE> --symlink --keep-workflow-wd --git-aware
