Hi, I have some questions about adding new custom tools to my Galaxy instance: 1- How can I reuse workflows? a. Should I wrap a workflow as a tool? b. Or can I just add a custom workflow as a workflow step in another workflow? 2- I noticed that option 1.b above seems to copy the complete workflow into my new workflow, so if I have an existing workflow A with N steps and want to use this in workflow B which already has M steps, I end up with a workflow that has M+N steps while I would expect M+1 steps... This behaviour gives me the impression that if I change workflow A, this will not automatically imply a change in workflow B. Is my interpretation correct? 3- If option 1.a above is the way to go for now, what are the steps to do this? E.g. what is the command to run a workflow from the command line? Thanks and regards, Pieter Lukasse.
