+This is a Galaxy tool wrapper for weblogo3 already available as a web app at the site below but neat as a Galaxy tool
+Last updated by Ross to install iuc ghostscript and numpy dependencies.
+
+Weblogo generates sequence logos from fasta files such as the alignments generated by clustalw
+
+Note that the image for the help must be in static/images for it to show up on the tool form - it's the same image as goes in test-data
+
+**Automated Installation**
+As a Galaxy admin, use the admin menu and select the search ToolShed option. This tool should be on the main toolshed - if not try the test toolshed.
+Select it and choose "preview and install" - the process of downloading and installing weblogo3.3 and this wrapper should take a few minutes at most.
+
+** Manual Installation**
+
+Don't.
+
+If you insist,
+Make sure weblogo3 is installed in your system python and is available on the path for all your nodes
+
+Move the test data files to your galaxy root test-data
+Move the xml file to a subdirectory of your tools folder (eg rgenetics/) and then add a line in your tool_conf.xml to point there.
+Run
+sh run_functional_tests.sh -id weblogo3
+to make sure the tests work
+
+then restart Galaxy and you should be good to go.

+
+**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:: $PATH_TO_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 exactly the same length!
+
+
+**Attribution**
+
+Weblogo attribution and associated documentation are available at Weblogo3_
+
+This Galaxy wrapper calls their software so depends on it and their license for your legal comfort.
+The wrapper was written by Ross Lazarus for the rgenetics project and the source code is licensed under the LGPL_ like other rgenetics artefacts

+            weblogo3 is a python version of the old weblogo2.8 or so. Requires numpy and ghostscript so these are installed if not already on your system - if that happens, please be patient
+            while numpy compiles - especially if the ATLAS libraries are being installed - which is not at present.
