+normalize and visualize Hi-C data.  HiCExplorer facilitates the creation of
+contact matrices, correction of contacts, TAD detection, A/B compartments,
+merging, reordering or chromosomes, conversion from different formats
+including cooler and detection of long-range contacts.  Moreover, it allows
+the visualization of multiple contact matrices along with other types of data
+like genes, compartments, ChIP-seq coverage tracks (and in general any type of
+genomic scores), long range contacts and the visualization of viewpoints.")
