-CALDER works on contact matrices in a three-column `dump` format as generated by the juicer dump command (https://github.com/aidenlab/juicer/wiki/Data-Extraction):	
+CALDER contains three modules: (1) compute chromatin domains; (2) derive their hierarchical organization and obtain sub-compartments; (3) compute nested sub-domains within each compartment domain.
