Tool Development

This module covers everything you need to start developing your own Galaxy Tools. This module will likely take you several days to complete.

Tutorial Video

Description:
  1. The first step to adding a tool to Galaxy, is to add it to (Bio)Conda. This tutorial will show you how to do that.
  2. Planemo is the Galaxy tool development kit, and will make your tool development process a lot easier! This tutorial will show you how to use Planemo to start the tool wrapping process, and covers the general structure of a Galaxy tool wrapper.
  3. You are now ready to start writing your tool wrapper! This video will show you how.
  4. Each tool wrapper also needs a .shed.yml file, which contains some metadata about the tool.
  5. Here you will learn how to test Galaxy tools using Planemo.
  6. Here you will learn how to publish tools in public tool repositories.
