Common Workflow Language User Guide: Setup

To follow the Common Workflow Language user guide, you will need an up-to-date Linux or Mac OS X system, with the following software installed:

• A text editor with YAML support
• A CWL implementation to run the described tools and workflows. When first getting started with CWL, we recommend the reference implementation, cwltool. You can find a full list on the project homepage.
• Most of the software tools used in the user guide are standard UNIX commands (cat, echo, env, tar, touch, wc), but to run all examples you will also need:
  • node.js
  • Java compiler
  • Docker (optional)
