If I understand your question correctly, there isn't currently a way to do this in Galaxy. I am working on a feature that will allow the selection of multiple inputs for each Input Dataset step, so that's potentially useful in the specific context you mention if you're willing to split apart your input file, but it wouldn't allow you to adjust other parameters. This is, however, something we've talked about implementing. -Dannon On Jan 19, 2011, at 5:00 AM, 조수안 wrote:

Hi, How can I execute a module with different input parameters in several nodes ? For example, there is a module that calculates chromosome length, and a input file that contains 25 chromosome sequences. When I execute the module for the input file, I want to execute the module in 25 nodes with each chromosome sequence. In this situation, when I make a workflow, can I place the module once in the workflow ? not placing the module 25 times.
