These files were created to practice with the tutorial and only contain data for chromosome 21 (and thus are very small files). This data is originally from Rao et al 2014, A 3D map of the human genome at kilobase resolution reveals principles of chromatin looping (https://doi.org/10.1016/j.cell.2014.11.021) and the full files are available for download from GEO (https://www.ncbi.nlm.nih.gov/geo/) under accession number GSE63525
