Plots the diagonal, and some values close to the diagonal of a Hi-C 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

Named 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

figure width in centimeters

Default: 40

–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

Resolution for the image in case theouput is a raster graphics image (e.g png, jpg)

Default: 72


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.

Default: 0.05

–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.
