The Mass Genome Annotation Data Repository

The Mass Genome Annotation (MGA) Data Repository stores published next generation sequencing data and other genome annotation data (such as gene start sites, SNPs, etc.) that, in conjunction with the ChIP-Seq and SSA servers, can be accessed and studied by scientists. The main characteristic of the MGA database is to store mapped data (in the form of genomic coordinates of mapped reads) and not sequence files. In this way, each sample present in the database has been pre-processed (for example sequence reads have been mapped to a genome) and presented in a standardized text format.大规模基因组注释（Mass Genome Annotation, MGA）数据集存储库，存储已发表的下一代测序（next generation sequencing, NGS）数据及其他基因组注释数据（例如基因起始位点、单核苷酸多态性（Single Nucleotide Polymorphisms, SNPs）等）。该存储库可与染色质免疫共沉淀测序（Chromatin Immunoprecipitation Sequencing, ChIP-Seq）服务器及SSA服务器协同工作，供科研人员访问并开展研究。MGA数据库的核心特征为存储比对后的数据（以比对后测序读段的基因组坐标形式呈现），而非原始序列文件。通过这种模式，数据库内的每一个样本均已完成预处理（例如将测序读段比对至参考基因组），并以标准化文本格式进行呈现。

背景概述

Mass Genome Annotation (MGA) 数据仓库存储已发布的下一代测序数据及其他基因组注释数据（如基因起始位点、SNPs等），其核心特点是存储映射数据（以基因组坐标形式）而非原始序列文件，数据经过预处理并以标准化SGA格式呈现。该数据库涵盖多种数据类型，包括ChIP-seq、转录谱分析等，覆盖人类、小鼠等多个生物体，总样本数超过38000个，可与ChIP-Seq和SSA服务器结合供科学研究使用。
