HiCEnterprise: Identifying long range chromosomal contacts in HiC data
Computational analysis of chromosomal capture data is currently gaining popularity with the rapid advance in experimental techniques providing access to growing body of data. An important problem in this area is the identification of long-range contacts be- tween distinct chromatin regions. Such loops were shown to exist at different scales, either mediating interactions between enhancers and promoters or providing much longer interactions between functionally interacting distant chromosome domains. A proper statistical analysis is crucial for accurate identification of such interactions from experi- mental data. We present HiCEnterprise, a software tool for identification of long-range chromatin contacts. It implements three different sta- tistical tests for identification of significant contacts at different scales as well as necessary functions for input, output and visualization of chromosome contact matrices.
