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?
