Hello all, I am working on integrating a few tools into Galaxy with multiple outputs. There are examples on the wiki for handling variable outputs determined by parameters and an arbitrary number of outputs, but none of them seemed to apply to this case. This tool must accept two lists of parameters a and b. The number of output files is (len(a) * len(b)) + 2. Is there a way to implement this in Galaxy without having to arbitrarily impose a limit on the length of the parameter lists? Also, if I would be required to use the arbitrary outputs mechanism, could the user still incorporate the output of this tool into workflows? Thank you.
