 A bed file of topologically-associating domains can be used, in which case only the breakpoints in the same TAD as a gene are considered in the search for enhancer hijacking events. One TAD file is provided in the data directory. If not TAD file is provided, pyjacker will instead look for breakpoints within a fixed distance to the gene (1.5Mb by default). See data/HSPC_TADs.bed for an example.
