Reproducibility in computational workflows can be generally enabled in two ways: either the workflow is packaged together with all its contents or shared as a recipe that can be followed to reproduce the results . MAW is an automated untargeted metabolomics workflow that incorporates both ways via CWL. CWL specifies workflow abstractions, integrates different tools and packages, and provides a complete, deployable, interoperable workflow description. The sharing, reuse, and archival of the source code, installation instructions, and tutorial for MAW is achieved via Zenodo, and WorkflowHub as the primary workflow registry. It is a free and open-source workflow, with all dependencies also being open-source (except for the annotation tool SIRIUS which is integrated into another version of the workflow for interested academic users).
