HUMAnN Collection Mapping Launch Failure

Hi @Reki

If you are working at UseGalaxy.eu, the odd behavior may have been related to this known issue, so please do try to run the tool again now. If resolved, please let us know! :hammer_and_wrench:

Known issue


Persistent issue

If you are working at a different server, or starting up the tool/workflow again now is still not possible, I’m wondering if there is a problem with how the collection data is organized, or maybe a problem within the workflow.

Some ideas about how to troubleshoot

  1. A workflow needs a few changes to run on individual samples versus a collection folder, so there will be at least two distinct workflow versions most of the time.
  2. The tool form has the different “select” options for individual, multiple, and collection input choices.
  3. There can be some logic constraints for the different collection folder shapes too.

This topic has some screenshots and descriptions for how to check:


I’m sure you know all of this but it hasn’t been summarized in one place in a while, so I’m borrowing your question! :man_scientist:

I’d like to review your use case! Would you like to share your history? → FAQ: Sharing your History.

This can be a subset of input data in a different history, or with tutorial data (good to compare against anyway). Just enough to trigger the behavior. Because the options will matter, please also post back some screenshots of the tool form with any relevant parameters set up. I’ll try to reproduce then make suggestions or we can probably come up with a workaround (and report the issues!). The tool version (top of tool form) should be captured, and the server URL will be in the share link.

You are correct that collections should be accepted but I’ll need to see the exact situation to offer advice. If you would rather post this in a direct message here instead of publically, please start one up! Then we can abstract the help back in the public threads.

Let’s start there! :slight_smile:
