## Copy number aberrations / Plot correlations of called copy number data

### Description

This tool calculates the correlations of copy number aberrations between different regions the the genome and plots them.

### Parameters

- Human genome build to use (GRCh37/hg19, NCBI36/hg18, NCBI35/hg17, NCBI34/hg16) [GRCh37/hg19]

### Details

Plotting the correlations can help to identify specific aberrations that often co-occur. Two gains that co-occur will have a positive correlation coefficient (plotted in blue), whereas a gain and a loss that co-occur will have a negative correlation coefficient (red).

This tool should be run after running the Identify common regions from called copy number data tool.

### Output

Two plots of the correlation matrix, one showing each region with the same size, and another showing each region according to their true genomic size. Also a numberic table of the correlation coefficients is produced.
