Hi, Holger, Thanks for reporting this. We might need some more information to sort this out. Is this error seen on Galaxy main or test? If so please share the history with me so I can see the input and reproduce what sounds like a wrapper error? Otherwise, if this is on a private instance, and if the tool has never produced output successfully, then this may be a dependency installation problem - eg you may need to ensure that the weblogo3 executable is available and working correctly on the path used by your execution nodes. To assure yourself that your data works with the tool, please try running it on main using the same data, and let me know what you see? Thanks again.

Dear all,
I have a problem with the weblogo tool. I have a clustalw alignment in fasta format that I'd like to visualize as a logo. The sequence logo module ends with a success (green box), the info tells me the amount and length of the input data. But the output is empty, there are no plots (no matter if I select jpg, png, pdf or text). The respective image can't be displayed "because it contains errors" or is empty in case of text.
I suspect that the actual call of the weblogo tool doesn't succeed, but I didn't figure out yet on how to check this. Does anybody have hints on where to look?
Cheers, Holger
