**What it does**

This tool calculates the genome-wide coverage of intervals defined in a BAM or BED file and reports them in BedGraph format.

.. image:: $PATH_TO_IMAGES/genomecov-glyph.png

.. class:: warningmark

The input BED or BAM file must be sorted by chromosome name (but doesn't necessarily have to be sorted by start position).

-----

**Example 1**

Input (BED format)-
Overlapping, un-sorted intervals::

    chr1    140 176
    chr1    100 130
    chr1    120 147


Output (BedGraph format)-
Sorted, non-overlapping intervals, with coverage value on the 4th column::

    chr1    100 120 1
    chr1    120 130 2
    chr1    130 140 1
    chr1    140 147 2
    chr1    147 176 1

-----

**Example 2 - with ZERO-Regions selected (assuming hg19)**

Input (BED format)-
Overlapping, un-sorted intervals::

    chr1    140 176
    chr1    100 130
    chr1    120 147


BedGraph output will contain five columns:

    * 1. Chromosome name (or 'genome' for whole-genome coverage)
    * 2. Coverage depth
    * 3. The number of bases on chromosome (or genome) with depth equal to column 2.
    * 4. The size of chromosome (or entire genome) in base pairs
    * 5. The fraction of bases on chromosome (or entire genome) with depth equal to column 2.

**Example Output**:
