Dive deeper into this product! Workflow engines run complex activities to enable large scale genomic analysis. The ability to execute the same scientific tools and workflows across different environments without modification is critical to reproducible research and open science. WES is a protocol that executes portable workflows in a preferred compute environment using data in a preferred storage environment, bringing greater flexibility to genomic analysis pipelines. A key feature of the WES API is that it promotes interoperability by abstracting over different workflow types and engines, thus enabling users to use the same client to trigger the execution of a wide range of portable workflows — regardless of whether they are written in the Common Workflow Language (CWL), the Workflow Definition Language (WDL), Nextflow, or Snakemake.
