-Availability
-============
-
-This workflow is available on the main Galaxy Tool Shed:
-http://toolshed.g2.bx.psu.edu/view/peterjc/rxlr_venn_workflow
-
-Development is being done on github here:
-https://github.com/peterjc/picobio/tree/master/galaxy_workflows/rxlr_venn_workflow
-
-
-Dependencies
-============
-
-These dependencies should be resolved automatically via the Galaxy Tool Shed:
- * http://toolshed.g2.bx.psu.edu/view/peterjc/tmhmm_and_signalp
- * http://toolshed.g2.bx.psu.edu/view/peterjc/seq_filter_by_id
- * http://toolshed.g2.bx.psu.edu/view/peterjc/venn_list
-
-However, at the time of writing those Galaxy tools have their own dependencies
-required for this workflow which require manual installation (SignalP v3.0,
-HMMER v2.0, and the R/Bioconductor package limma).

+Galaxy tool to draw a Venn Diagram with up to 3 sets
+====================================================
+
+This tool is copyright 2011 by Peter Cock, The James Hutton Institute
+(formerly SCRI, Scottish Crop Research Institute), UK. All rights reserved.
+See the licence text below.
+
+This tool is a short Python script (using both the Galaxy and Biopython library
+functions) to extract ID lists from tabular, FASTA, FASTQ or SFF files to build
+sets, which are then drawn using the R limma package function vennDiagram
+(called from Python using rpy).
+
+There are just two files to install:
+
+* venn_list.py (the Python script)
+* venn_list.xml (the Galaxy tool definition)
+
+The suggested location is in the Galaxy folder tools/plotting next to other
+graph drawing tools.
+
+You will also need to modify the tools_conf.xml file to tell Galaxy to offer the
+tool. The suggested location is in the "Graph/Display Data" section. Simply add
+the line:
+
+<tool file="plotting/venn_list.xml" />
+
+You will also need to install Biopython 1.54 or later, and the R/Bioconductor
+pacakge limma. You should already have rpy installed for other Galaxy tools.

+
+**TIP:** If your data is in tabular files, the identifier is assumed to be in column one.
+
+**What it does**
+
+Draws Venn Diagram for one, two or three sets (as a PDF file).
+
+You must supply one, two or three sets of identifiers -- corresponding
+to one, two or three circles on the Venn Diagram.
+
+In general you should also give the full list of all the identifiers
+explicitly. This is used to calculate the number of identifers outside
+the circles (and check the identifiers in the other files match up).
+The full list can be omitted by implicitly taking the union of the
+category sets. In this case, the count outside the categories (circles)
+will always be zero.
+
+The identifiers can be taken from the first column of a tabular file
+(e.g. query names in BLAST tabular output, or signal peptide predictions
+after filtering, etc), or from a sequence file (FASTA, FASTQ, SFF).
+
+For example, you may have a set of NGS reads (as a FASTA, FASTQ or SFF
+file), and the results of several different read mappings (e.g. to
+different references) as tabular files (filtered to have just the mapped
+reads). You could then show the different mappings (and their overlaps)
+as a Venn Diagram, and the outside count would be the unmapped reads.
+
+**Citations**
+
+The Venn Diagrams are drawn using Gordon Smyth's limma package from
+R/Bioconductor, http://www.bioconductor.org/
+
+The R library is called from Python via rpy, http://rpy.sourceforge.net/
