EDD: a program for detection of wide genomic enrichment domains robust against local variations [RNA-Seq]

Nuclear lamins contact the genome at the nuclear periphery through large domains and are involved in chromatin organization. Among broad peak calling algorithms available to date, none are suited for mapping lamin-genome interactions genome-wide. We disclose a novel algorithm, Enriched Domain Detector (EDD), for analysis of broad enrichment domains from ChIP-seq data. EDD enables discovery of genomic domains interacting with broadly distributed chromatin-associated proteins such as lamins. The main advantage of EDD over existing broad peak callers is sensitivity to domain width rather than enrichment strength at a particular site, and robustness against local variations. EDD is downloadable from http://github.com/eivindgl/edd.

核纤层蛋白（Nuclear lamins）通过大型结构域与核外周的基因组发生接触，并参与染色质组织过程。截至目前，现有广谱峰调用算法均无法完成全基因组范围内核纤层蛋白与基因组互作的图谱绘制。我们研发了一款全新算法——富集结构域检测器（Enriched Domain Detector, EDD），用于分析染色质免疫共沉淀测序（ChIP-seq）数据中的广谱富集结构域。该算法可用于识别与核纤层蛋白等广谱分布的染色质结合蛋白存在互作的基因组结构域。相较于现有广谱峰调用工具，EDD的核心优势在于其对结构域宽度而非特定位点富集强度的敏感性，且对局部变异具备优异的鲁棒性。该工具可通过http://github.com/eivindgl/edd下载获取。
