EDD: a program for detection of wide genomic enrichment domains robust against local variations [ChIP-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）通过大片段结构域在核膜边缘与基因组结合，并参与染色质组织。截至目前，现有宽峰检测算法均无法适用于全基因组范围内核纤层蛋白-基因组互作的图谱绘制。我们提出了一款全新算法——富集结构域检测器（Enriched Domain Detector，EDD），用于分析ChIP-seq数据中的宽富集结构域。该算法可鉴定与核纤层蛋白这类广泛分布的染色质结合蛋白互作的基因组结构域。相较于现有宽峰检测工具，EDD的核心优势在于其关注结构域宽度而非单个位点的富集强度，且对局部变异具备更强的鲁棒性。用户可从http://github.com/eivindgl/edd下载EDD。

背景概述

该数据集描述了EDD（Enriched Domain Detector）算法，这是一个用于从ChIP-seq数据中检测广泛基因组富集域的新工具，特别适用于研究核纤层蛋白与基因组的相互作用。其关键特点在于对域宽敏感而非富集强度，且对局部变化具有鲁棒性，数据集包含5个样本但未提供详细元数据。
