Plot Viewpoint
==============

**hicPlotViewpoint** plots the number of interactions around a specific reference point or region in the genome like a 4C analysis using Hi-C data.
This plotting method allows to make long-range interactions more visible.

_________________

Usage
-----

This tool must be used on Hi-C contact matrices corrected using ``hicCorrectMatrix``.

_________________

Output
------

**hicPlotViewpoint** outputs an image with the plotted interactions around the reference point in png or svg format, an example plot can be found bellow. An option allows to also output the interactions as a bedgraph file.
