Plots the diagonal, and some values close to the diagonal of a HiC matrix. The diagonal of the matrix is plotted horizontally for a region. I will not draw the diagonal for the whole chromosome

usage: hicPlotTADs --tracks tracks.ini --region chr1:1000000-4000000 -o image.png
optional arguments
--tracks File containing the instructions to plot the tracks
--region Region to plot, the format is chr:start-end
--BED Instead of a region, a file containing the regions to plot, in BED format, can be given. If this is the case, multiple files will be created using a prefix the value of –outFileName
--width=40 figure width in centimeters
--height Figure height in centimeters. If not given, the figure height is computed based on the widths of the tracks and on the depth of the Hi-C tracks, if any. Setting this this parameter can cause the Hi-C tracks to look collapsed or expanded.
--title, -t Plot title
--scoreName, -s
 Score name
--outFileName, -out
 File name to save the image, file prefix in case multiple images are stored
--zMax zMax
--vlines Genomic cooordindates separated by space. E.g. –vlines 150000 3000000 124838433
--fontSize Font size for the labels of the plot
--dpi=72 Resolution for the image in case theouput is a raster graphics image (e.g png, jpg)
 By default the space dedicated to the track labels is 0.05 of theplot width. This fraction can be changed with this parameter if needed.
--version show program’s version number and exit

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 in a configuration file. Once the tracks file is ready, hicPlotTADs can be used as follows:

$ hicPlotTADs --tracks tracks.ini --region chr1:1,000,000-2,000,000  -o tads.pdf

The following is a template for the configuration file which is based on .ini configuration files. Each track is defined by a section header (for example [hic track]), followed by parameters specific to the section as color, title, etc.

# lines that start with '#' are comment lines
# and are not interpreted by the program
# the different tracks are represented by sections in this file
# each section starts with a header of the form [hic]
# the content of the section label (in the previous example 'hic') is irrelevant for
# plotting and only used to tell the user when something goes wrong.
# There are two exceptions for this, the [x-axis] and the [spacer] sections
# that use the section label to determine the action.
