Question: How To Re-Use A Parameter In A Workflow?

Galaxy Users, I have a workflow where I'd like the user to input a value once, say a number of nucleotides. That value would then be used as an input parameter to several different tasks, for example, to two instances of "Operate on Genomic Intervals > Get flanks" , where it would be used both for the "offset" and "length of flanking regions(s)" in one instance, and it's value and it's *negative* would be used for the second instance. Thus, the user inputs "20", and Get_flanks(20,20) and Get_flanks(-20,20) get run. For this workflow, it's important that those parameters all be of the same magnitude, or things will get messy later, so I don't want the user having to input them separately, or to have to remember which one gets negated... All suggestions welcome, Curtis

Hi Curtis, In the workflow editor, you can specify a parameter name within the text boxes for the tool inputs that you want to be set at runtime to the same value. This is done using notation like "${A user entered value}", as seen in these screen shots: Please let us know if we can provide further assistance. Thanks for using Galaxy, Dan

Daniel, Great. That exactly and perfectly solves my problem! Thanks so much.

Hi,

I encounter the same problem and your screenshots aren't visible anymore. Is this answer still valid ?
