**Note**

This tool uses Weblogo3_ in Galaxy to generate a sequence logo. The input file must be a fasta file in your current history.

It is recommended for (eg) viewing multiple sequence alignments output from the clustalw tool - set the output to fasta and feed
it in to this tool.

A typical output looks like this

.. image:: ./static/images/rgWebLogo3_test.jpg

----

**Warning about input Fasta format files**

The Weblogo3 program used by this tool will fail if your fasta sequences are not all EXACTLY the same length. The tool will provide a warning
and refuse to call the weblogo3 executable if irregular length sequences are detected.

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 
sequences are the same length!
