Hi everyone First let me thank all the Team Galaxy, the conference was really great. Kanwei asked me to send the tool I told him about. It's one of these tools for which you can't know the exact number of output datasets before tool run. Here are the files. It's really simple actually, but it would be nice if I could integrate it in workflows without it having to be the final step. Would it even be possible? And please ignore the idiotic comments in the files, I was really tired that day. Cheers, L-A
