+
+**This is a modified version of the standard Galaxy toolshed "MACS2" tool,
+which has been customised for users at the University of Manchester to work
+with MACS 2.1.0.**
+
+It is based on the 16:14f378e35191 revision of the tool at
+
+ *  http://toolshed.g2.bx.psu.edu/view/modencode-dcc/macs2 
+
+------
+
+**What it does**
+
+With the improvement of sequencing techniques, chromatin immunoprecipitation
+followed by high throughput sequencing (ChIP-Seq) is getting popular to study
+genome-wide protein-DNA interactions. To address the lack of powerful ChIP-Seq
+analysis method, we present a novel algorithm, named Model-based Analysis of
+ChIP-Seq (MACS), for identifying transcript factor binding sites. MACS captures
+the influence of genome complexity to evaluate the significance of enriched
+ChIP regions, and MACS improves the spatial resolution of binding sites through
+combining the information of both sequencing tag position and orientation. MACS
+can be easily used for ChIP-Seq data alone, or with control sample with the
+increase of specificity.
+
+View the original MACS2 documentation:
+https://github.com/taoliu/MACS/blob/master/README.rst
+
+------
+
+**Usage**
+
+**Peak Calling**: Main MACS2 Function to Call peaks from alignment results.
+
+**Compare .bdg files**: Deduct noise by comparing two signal tracks in bedGraph.
