Hello, I'm working with two custom tools in my local galaxy instance: The first tool outputs a single aceb file. aceb is a custom datatype I've added that describes a crop experiment. The second tool takes three files as inputs, one of which is an aceb file. I can successfully run these two tools together in Galaxy outside of a workflow. But for some strange reason I cannot connect these two tools in the workflow editor. The connection never turns green and links. Here are the relevant lines in the tool wrappers: Outputs of first tool: <outputs> <data format="aceb" name="acebData" label="Experiment data with unified format" /> </outputs> Inputs of second tool: <inputs> <param name="acebData" type="data" format="aceb" label="Inut Survey aceb Data" /> <param name="domeData" type="data" format="dome" label="Input Strategy DOME Data" /> <param name="linkData" type="data" format="txt" label="Input Linkage between field overlay and survey" /> </inputs> Any ideas for what could be causing this? Thanks. David
