 What it does
---------------
+------------
 
 This tools takes the default output of ``multiBamSummary`` or ``multiBigwigSummary``, and computes the pairwise correlation among samples.
-Results can be visualized as **scatterplots** or as
-a **heatmap** of correlation coefficients (see below for examples).

+Theoretical Background
+----------------------
 
 The result of the correlation computation is a **table of correlation coefficients** that indicates how "strong" the relationship between two samples is and it will consist of numbers between -1 and 1. (-1 indicates perfect anti-correlation, 1 perfect correlation.)

 Output
---------
+------
 
 The default output is a **diagnostic plot** -- either a scatterplot or a clustered heatmap displaying the values for each pair-wise correlation (see below for example plots).
 
 Optionally, you can also obtain a table of the pairwise correlation coefficients.
