Hi all, Just a heads-up, I had a tool.xml file in which a command line was called with a parameter called —type. I therefore set <param name=“type” type=“select > etc etc. to do: command —type $type Big mistake. This lead to errors as soon as the tool was modified in the workflow (set as runtime triggered an error for me), due to the fact that the workflow module type was not one of tool, data input, data collection, but was instead the value of the type param which was currently filled in. Now I know not to do this, hope you already did. cheers, — Jorrit Boekel Proteomics systems developer BILS / Lehtiö lab Scilifelab Stockholm, Sweden ___________________________________________________________ Please keep all replies on the list by using "reply all" in your mail client.
