**What it does**

bedtools flank will optionally create flanking intervals whose size is user-specified fraction of the original interval.

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

.. class:: warningmark

In order to prevent creating intervals that violate chromosome boundaries, bedtools flank requires a genome file defining the length of each chromosome or contig.
