Workflow: Metagenomics

Create a Galaxy workflow

Galaxy provides the option to extract a workflow based on the steps you just followed and the tools and parameters used.

New to Galaxy? First try the introduction and then learn some key tasks

Metagenomics

  • Log in to your Galaxy instance (for example, Galaxy Australia, usegalaxy.org.au).

Before we create a workflow for metagenomics, we need the correct files in our current Galaxy history. We can get these files in two ways:

  • Either follow the tutorial on Metagenomics

  • Or, obtain the files from a Shared History (Galaxy Australia only).

    • Go to Shared Data
    • Click Histories
    • Click Completed-soil-metagenomics-analysis
    • Click Import (at the top right corner)
    • The analysis should now be showing as your current history.

When you have completed this tutorial or imported the history, you will have the correct files in your history panel.

Extract the Workflow

  • In the history panel, click on the cog icon.
  • Click Extract Workflow
  • If all looks ok, click Create Workflow
  • In the centre panel, click edit
  • This brings up the workflow canvas, a space for graphically viewing and re-arranging your workflow.
  • Drag the panes around until your workflow is clear.
  • Click on the star icon next to any output files that you want to retain.
  • In the top right corner click on the cog icon and Save

  • This workflow will now run.
  • In the History panel, click on the View all histories icon view hist
  • Find your workflow history and Switch to it.

To see all your workflows, go to the top panel in Galaxy and click Workflow.
