 **What it does**
 
 This tools takes a compressed matrix of scores (such as read coverages) for a number of genomic regions
-and different samples. It can visualize the correlation among samples as scatterplots or as
+and different samples. It can visualize the correlation among samples as scatterplots or as 
 heatmap of correlation coefficients. Further output files are optional.
 The compressed input matrices are easily generated using the "bamCorrelate" and "bigwigCorrelate" modules of deeptools.

 **Output files**:
 
-- **diagnostic plot**: Either a scatterplot or clustered heatmap (select above) displaying the values for each pair-wise correlation,

+- **correlation structure**: a scatterplot of all mutual correlations between all samples in matrix
+- **diagnostic plot**: clustered heatmap displaying the values for each pair-wise correlation, see below for an example
 - data matrix (optional): if you want to analyze or plot the correlation values using a different program, e.g. R, this matrix can be used
 
-**Output with test dataset**:
-
-Following is the output of plotCorrelation with our test ChIP-Seq datasets. Average coverages were computed over 10kb bins for chromosome X,
-from bigwig files using bigwigCorrelate. The output was used by plotCorrelation to make a heatmap of spearman correlation between samples.
