Plot Topologic Associated Domains
=================================

**hicPlotTADs** is a visualization tool to plot the topologically associating domains (TADs) in a given region. Additional tracks can be added to enable the comparisons with other data like gene, ChIP-seq, RNA-seq or other tracks, including TAD seperation scores computed by ``hicFindTADs``.

_________________

Usage
-----

This tool takes various types of tracks as input:

    - **TAD vizualisation:** corrected Hi-C contact matrix to plot a contact heatmap. It is recommended to follow ``hicPlotMatrix`` instructions. Boundaries file can used, which is the output of ``hicFindTADs`` in bed format. If selected, TADs will be drawn directly on the contact heatmap.
    - **Chromatin states:** display blocks of different colors following a bed file.
    - **TAD score:** display TAD seperation score computed by ``hicFindTADs``.
    - **Gene track / Bed Track:** display genes or bed files. Labels like gene names can be toggled on or off.
    - **Bigwig track:** generic bigwig track plotting.
    - **Bedgraph track:** generic bedgraph track plotting.
    - **Bedgraph matrix track** is used to specifically plot bm files computed by ``hicFindTADs`` (TAD seperation scores).
    - **Vlines:** vertical lines drawn on top of all tracks following a bed file. It is used as a visual support where regions start / end over all tracks, for example to display TAD boundaries computed by ``hicFindTADs``.
    - **Spacer:** Add some space between two tracks.

For each track, parameters for the color, the width or the font size can be defined.

_________________

Output
------

**hicPlotTADs** output is similar to a genome browser screen-shot that besides the usual genes, and score data (like bigwig or bedgraph files) also contains Hi-C data. The plot is composed of tracks that need to be specified.
Below is represented the 85 Mb to 110 Mb region from human chromosome 2 visualized using **hicPlotTADs**. TADs were computed by ``hicFindTADs``. The additional tracks added correspond to: TAD-separation score (as reported by ``hicFindTADs``), chromatin states, principal component 1 (A/B compartment) computed using ``hicPCA``, ChIP-seq coverage for the H3K27ac mark, DNA methylation, and a gene track. Data are from mouse cardiac myocytes, published by `Nothjunge et al. (2017)`_.
