Transformation of matrix for plotting
=====================================

**hicTransform** computes three matrices based on one Hi-C contact matrix as input based on the methods determined by `Lieberman-Aiden et al. (2009)`_:

- An **observed/expected matrix** obtained "by dividing each entry in the contact matrix by the genome-wide average contact probability for loci at that genomic distance" (`Lieberman-Aiden et al. (2009)`_). This transformation allows to better assess long range interactions.
- A **Pearson correlation matrix** obtained by computing the Pearson correlation between each bin based on observed/expected values. This matrix transformation allows to better identify the bins that are entering in contact together, or not, at long ranges, and thus helps defining compartments in the nucleus (``hicPCA``).
- A **covariance matrix**, which is used as a basis for the Principal Component Analysis (PCA) to compute the eigenvectors outputed by **hicTransform**.

These three matrices can be used with ``hicPlotMatrix`` or ``hicPlotTADs`` for a visualization of the A / B compartment analysis.

Output
------

From one Hi-C contact matrix, **hicTransform** outputs the observed/expected, Pearson correlation and covariance matrices.
