Contact matrix plot
=======================

``hicPlotMatrix`` is a visualization tool for a contact matrix. It supports to plot the whole contact matrix, one or more chromosomes, a region or two regions against each other.
 Additional it can plot the result of a principal component analysis to have a better understanding of A / B compartments.

Input
-----

Parameters
__________
- the contact matrix: h5 or cool file format.
- A title for the plot
- Score name
- per chromosome
- The chromosomes to include in the plot. 
- What to show: 
- The region(s) to plot. This parameter overrides 'chromosome'. If either 'chromosomes' or 'region' is given the full contact matrix is used.
- log / log1p of the values: It is recommended to use log1p.
- Colormaps_ for the heatmap. 
- vMin / vMax
- principal component: a bedgraph or bigwig file containing eigenvector information

Output
------

The contact matrix plotted for chromosome 1.

The contact matrix used with ``--perChr`` and the first eigenvector from the tool ``hicPCA``. For this plot a pearson correlated matrix was used which is computed by creating first an observed / expected matrix and second a pearson correlation matrix. These matricies can be computed with ``hicChangeMatrixType``. The used Hi-C data were published by `Lieberman-Aiden <https://doi.org/10.1126/science.1181369>`_ in 2009, `GSE18199 <https://www.ncbi.nlm.nih.gov/geo/query/acc.cgi?acc=GSE18199>`_.
