Workflows are a powerful Galaxy feature that allows you to scale up your analysis by performing an end-to-end analysis with a single click of a button. In order to keep provenance of the workflow invocation (an invocation of a workflow means one run or execution of the workflow) it can be exported from Galaxy in the form of a Workflow Run Crate RO-Crate profile.
AgendaIn this tutorial, you will learn how to create a git repo, and begin working with it.
Additionally, the exported Workflow Run Crate allows for sharing workflow run provenance with those unfamiliar with Galaxy and its standard export format.
This tutorial will guide you through the steps of defining such a report for your workflow, .
This tutorial will show you how to generate Galaxy-based Workflow Run RO-Crate after running the workflow.
Hands-on: Choose Your Own TutorialThis is a "Choose Your Own Tutorial" section, where you can select between multiple paths. Click one of the buttons below to select how you want to follow the tutorial
Are you running Galaxy locally ?
Enable RO-Crate on your local instance
Hands-on: Update your galaxy configuration
- Go to where your Galaxy folder is in your computer
- In your root Galaxy folder navigate to the
config
folder where a thegalaxy.yml
should be located. Please open it.- (In case you only find a
galaxy.yml.sample
file, copy this one and name itgalaxy.yml
)- make sure the option
enable_celery_tasks
is set totrue
:galaxy: enable_celery_tasks: true
That’s it ! Now you can launch your local instance as usual.
Import an example workflow
For this tutorial, we will use the workflow from the Galaxy 101 for everyone tutorial. If you have not done this tutorial yet, the only thing you need to know is that this is a workflow that takes as input a table of data about different species of iris plants, this table is subsequently sorted and filtered, and some plots are made. The specifics of the workflow are not important for this tutorial, only that it outputs a number of different kinds of outputs (images, tables, etc).
We will start by importing this workflow into your Galaxy account:
Hands-on: Import the workflow
Import the workflow into Galaxy
Hands-on: Importing and launching a GTN workflow
- Click on Workflow on the top menu bar of Galaxy. You will see a list of all your workflows.
- Click on galaxy-upload Import at the top-right of the screen
- Paste the following URL into the box labelled “Archived Workflow URL”:
https://training.galaxyproject.org/training-material/topics/galaxy-interface/tutorials/workflow-reports/workflows/galaxy-101-everyone.ga
- Click the Import workflow button
Below is a short video demonstrating how to import a workflow from GitHub using this procedure:
Run the workflow
Galaxy will produce several export options for any workflow. The default export gives us a serialization of the invocation data model while the RO-Crate export gives an Workflow Run Crate which includes the default export as well.
Let’s run the workflow and export the RO-Crate.
Hands-on: Run the workflow
Import the file
iris.csv
via linkhttps://zenodo.org/record/1319069/files/iris.csv
- Copy the link location
Click galaxy-upload Upload Data at the top of the tool panel
- Select galaxy-wf-edit Paste/Fetch Data
Paste the link(s) into the text field
Press Start
- Close the window
- Run GTN Training: Galaxy 101 For Everyone workflow using the following parameters:
- “Send results to a new history”:
No
- “1: Iris Dataset”“: the
iris.csv
file we just uploaded
- Click on Workflow on the top menu bar of Galaxy. You will see a list of all your workflows.
- Click on the workflow-run (Run workflow) button next to your workflow
- Configure the workflow as needed
- Click the Run Workflow button at the top-right of the screen
- You may have to refresh your history to see the queued jobs
- View the workflow outputs once the workflow has completed
- The workflow produces several text and tabular outputs, and two plot (image) outputs
Export the Workflow Run Crate
After the workflow has completed, we can export the RO-Crate. The crate does not appear in your history, but can be accessed from the galaxy-history-options -> Show Invocations menu on the top right of your history OR on the left pannel from the galaxy-panelview Workflow Invocations .
Hands-on: Export the Workflow Run Crate
In the top right of your history, go to galaxy-history-options -> Show Invocations
- Our latest workflow run should be listed at the top.
- Click on it to expand it:
Click on the Export tab in the expanded view of the workflow invocation.
- Click on the Export tab in the expanded view of the workflow invocation. You should see a page that contains three download options: - Research Object Crate (RO-Crate) - BioCompute Object - File
Click on the Generate galaxy-download option of the RO-Crate box (1st box)
Great work! You have created a Workflow Run Crate. This makes it easy to track the provenance of the executed workflow.
