Workflow Description Language local runner & developer toolkit for Python 3.8

Installation requires Python 3.8 , pip3 (or conda) and Docker (or Podman/Singularity/udocker). Linux preferred; macOS (Intel) compatible with extra steps. More detail in full documentation.

• Install with pip : run pip3 install miniwdl
• Install with conda : run conda install -c conda-forge miniwdl
• Verify your miniwdl installation: miniwdl run_self_test
• Install from source code: see the Dockerfile for dependencies to run setup.py

Run an example bioinformatics WDL pipeline using miniwdl, or learn more abut miniwdl via a short course (screencast examples). If you are new to the WDL language, see the open source learn-wdl course.

• Run an example using a viral genome assembly workflow
• Learn miniwdl course w/screencasts - shown below
• Learn WDL course w/screencasts

The online documentation includes a user tutorial, reference manual, and Python development codelabs:

See the Releases for change logs. The Project board shows the current prioritization of issues.

The miniwdl runner schedules WDL tasks in parallel up to the CPUs & memory available on the local host; so a more-powerful host enables larger workloads. Separately-maintained projects can distribute tasks to cloud & HPC backends with a shared filesystem:

• AWS:
  • miniwdl-omics-run tool for the Amazon Omics workflow service
  • AWS Batch plugin (DIY)
• SLURM

• Open an issue
• OpenWDL Slack (#miniwdl channel)
• Bioinformatics Stack Exchange

Feedback and contributions to miniwdl are welcome, via issues and pull requests on this repository. See CONTRIBUTING.md for guidelines and instructions to set up your development environment.
