**What it does**

This tool is useful to assess the overall similarity of different BAM files. A typical application
is to check the correlation between replicates or published data sets.

The tool splits the genomes into bins of given length. For each bin, the number of reads
found in each BAM file is counted and a correlation (either Pearson or Spearman) is computed for all
pairs of BAM files. Finally, a heatmap is drawn based on the similarity of the samples.

You can find more details on the bamCorrelate wiki page: https://github.com/fidelram/deepTools/wiki/QC#wiki-bamCorrelate


**Output files**:

- **diagnostic plot**: clustered heatmap displaying the values for each pair-wise correlation, see below for an example
- data matrix (optional): if you want to plot the correlation values using a different program, e.g. R, this matrix can be used
