+The Weblogo3 program used by this tool will fail if your fasta sequences are not all EXACTLY the same length.
+
+Fasta alignments from the companion ClustalW Galaxy tool will work but many other fasta files may cause this tool to fail - please do not file
+a Galaxy bug report - this is a feature of the tool and a problem with your source data - not a tool error - please make certain all your fasta
