总结:最近开发的将下一代测序与基于染色体构象捕获的技术(如Hi-C和ChIA-PET)相结合的方法允许表征全基因组染色质3D结构。了解染色质的三维结构是解开全球基因调控的关键下一步,需要分析这些数据的方法。我们开发了HiBrowse,一个用户友好的网络工具,包括一系列基于假设和描述性统计,使用零模型中的现实假设。可用性和实现:所有主流浏览器都支持HiBrowse,并且可以在http://hyperbrowser.uio.no/3d上免费获得。软件是用Python实现的,源代码可通过主网站上的说明下载。联系方式:jonaspau@ifi.uio.no补充信息:补充数据可在生物信息学在线获得。
Summary: Recently developed methods that couple next-generation sequencing with chromosome conformation capture-based techniques, such as Hi-C and ChIA-PET, allow for characterization of genome-wide chromatin 3D structure. Understanding the organization of chromatin in three dimensions is a crucial next step in the unraveling of global gene regulation, and methods for analyzing such data are needed. We have developed HiBrowse, a user-friendly web-tool consisting of a range of hypothesis-based and descriptive statistics, using realistic assumptions in null-models. Availability and implementation: HiBrowse is supported by all major browsers, and is freely available at http://hyperbrowser.uio.no/3d. Software is implemented in Python, and source code is available for download by following instructions on the main site.
