Existing computational methods focus on intrachromosomal interactions and ignore interchromosomal interactions partly because there is no prior knowledge for interchromosomal interactions and the frequency of interchromosomal interactions is much lower while the search space is much larger. With the development of single-cell technologies, the advent of single-cell Hi-C makes interrogating the spatial structure of chromatin at single-cell resolution possible. It also brings a new type of frequency information, the number of single cells with chromatin interactions between two disjoint chromosome regions.<\/jats:p>\n              <\/jats:sec><jats:sec>\n                <jats:title>Results<\/jats:title>\n                <jats:p>Considering the lack of computational methods on interchromosomal interactions and the unsurprisingly frequent intrachromosomal interactions along the diagonal of a chromatin contact map, we propose a computational method dedicated to analyzing interchromosomal interactions of single-cell Hi-C with this new frequency information. To the best of our knowledge, our proposed tool is the first to identify regions with statistically frequent interchromosomal interactions at single-cell resolution. We demonstrate that the tool utilizing networks and binomial statistical tests can identify interesting structural regions through visualization, comparison and enrichment analysis and it also supports different configurations to provide users with flexibility.<\/jats:p>\n              <\/jats:sec><jats:sec>\n                <jats:title>Conclusions<\/jats:title>\n                <jats:p>It will be a useful tool for analyzing single-cell Hi-C interchromosomal interactions.<\/jats:p>\n              <\/jats:sec>","DOI":"10.1186\/s12859-020-03689-x","type":"journal-article","created":{"date-parts":[[2020,9,30]],"date-time":"2020-09-30T08:05:22Z","timestamp":1601453122000},"update-policy":"http:\/\/dx.doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":8,"title":["Network-based method for regions with statistically frequent interchromosomal interactions at single-cell resolution"],"prefix":"10.1186","volume":"21","author":[{"given":"Chanaka","family":"Bulathsinghalage","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Lu","family":"Liu","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"297","published-online":{"date-parts":[[2020,9,30]]},"reference":[{"key":"3689_CR1","doi-asserted-by":"publisher","first-page":"65","DOI":"10.1016\/j.ymeth.2014.10.031","volume":"72","author":"BR Lajoie","year":"2015","unstructured":"Lajoie BR, Dekker J, Kaplan N.
