Matrix correction
==================

``hicCorrectMatrix`` runs Dekker's iterative correction over a Hi-C matrix (`Imakaev 2012`_.). For correcting the matrix, 
it is important to remove the unassembled scaffolds (e.g. `NT_`), mitochondrial DNA and Y chromosome and keep only 
chromosomes, as scaffolds create problems with matrix correction. Therefore 
we use the chromosome names (1-19, X, Y) here. 
 
**Important**: Use ‘chr1 chr2 chr3 etc.’ if your genome index uses chromosome names with the ‘chr’ prefix.

Matrix correction works in two steps: first a histogram containing the sum of contact  per bin (row sum) is produced. This plot needs to be inspected to decide the best threshold for removing bins with lower number of reads. The second steps removes the low scoring bins and does the correction.

Input
-----


Diagnostic plot
~~~~~~~~~~~~~~~~
Plots a histogram of the coverage per bin together with the
modified z-score based on the median absolute deviation
method.

Parameters
__________
- the contact matrix
- Max value for the x-axis in counts per bin
- include chromosomes


Correct
~~~~~~~

Run the iterative correction. 

Parameters
__________

- remove bins of low coverage
- remove bins of large coverage
- include chromosomes

Output
------
