Hi Jennifer, Thanks for the reply. However, my question was not about building tools. My question was about building a workflow (using the workflow editor with existing tools), as a user of galaxy.
Using the workflow editor, when I create a workflow using a tool that allows a variable number of inputs, it seems that I have to define the number of inputs during workflow creation and not when I run the workflow. I was just asking if it would be feasible to have a variable number of inputs (only defined when a running instance of a workflow is created). It feels to me that the answer is no.
