What it does
-------------

This tool is useful to **assess the sequencing depth** of a given sample.
It samples 1 million bp, counts the number of overlapping reads and reports
a coverage histogram that tells you how many bases are covered how many times.

**Note:** Multiple BAM files are accepted but all should correspond to the same genome assembly.

Output
---------

The default output is a **panel of two plots** (see below for an example): One is a density plot visualizing the frequencies of read coverages, the other one lets you estimate what fraction of the genome has a depth of sequencing of, for example, 2 overlapping reads or more.

The optional output is a table where each row represents the number of reads overlapping with a sampled bp.
