Hello Pieter, When you install a repository into Galaxy that contains workflows, you can import the workflow into Galaxy. At the time the workflow is imported, the import process checks to see if all required tools are available in Galaxy. If not, a page is displayed with links to accessible Tool Sheds allowing the user to search for missing required tools. I believe this still works, although there have been some changes to the workflow framework over the past several months, and I have not checked to see if this is still available. See https://wiki.galaxyproject.org/ToolShedWorkflowSharing for more details. This approach is basically a "hack" that I implemented several years ago. A much better approach would be to enhance the workflow UI to include a feature allowing the user to search Tool Sheds to discover and install missing tools required by any workflow currently abvailable in the Galaxy instance. Hopefully at some point soon something like this will be introduced. Greg Von Kuster On Mar 25, 2014, at 6:47 AM, "Lukasse, Pieter" <pieter.lukasse@wur.nl> wrote:

Hi Bjoern,

I think you may have misunderstood me. What I mean is : instead of me having to add a tool_dependencies or repository_dependencies.xml to the workflows package, let Galaxy Tool Shed find these dependencies based on metadata available in the workflow itself.

Best regards,

Pieter.

Hi Pieter,

if I'm not misunderstood you, thats already possible:

Have a look at: https://github.com/bgruening/galaxytools/tree/master/workflows/glimmer3

For an example. Cheers, Bjoern

Hi Greg,

Do you have any plans of resolving the dependencies automatically when it comes to workflows? E.g. I have a Tool Shed repository where I would like to add workflows that are constructed using tools from different repositories. It would be nice if you could let Tool Shed install the tools automatically upon installation of the workflow. Any plans?

Best regards,

Pieter

Hi Pieter,

thanks for your prims Galaxy contributions. Any chance to add a repository_dependencies.xml file to the workflow repository?

Thanks, Bjoern
