The hicPlotTADs output is similar to a genome browser screenshot 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 track file is ready, hicPlotTADs can be used as follows:
$ hicPlotTADs --tracks tracks.ini --region chrX:99,974,316-101,359,967 \ -t 'Marks et. al. TADs on X' -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. For details please see the documentation of pyGenomeTracks.
$ hicPlotTADs --tracks hic_track.ini -o hic_track.png --region chrX:2500000-3500000
