ArrayExpress介绍
GEO数据库类似，ArrayExpress是属于EBI旗下的公共数据库，用于存放芯片和高通量测序的相关数据。
ArrayExpress是主要科学期刊推荐的存储库之一，用于存储来自微阵列和测序平台的功能基因组学数据，以支持可重复的研究。 为了完成这项任务，我们根据关于微阵列实验的最低信息（MIAME）和关于测序实验的最低信息（MINSEQE）指南来促进提交。 实验直接提交给ArrayExpress或从NCBI Gene Expression Omnibus数据库导入。 对于基于高通量测序的实验，原始数据可以转发到欧洲核苷酸档案库，而实验描述和处理过的数据则存储在ArrayExpress中。
ArrayExpress is a new public database of microarray gene expression data at the EBI, which is a generic gene expression database designed to hold data from all microarray platforms. ArrayExpress uses the annotation standard Minimum Information About a Microarray Experiment (MIAME) and the associated XML data exchange format Microarray Gene Expression Markup Language (MAGE-ML) and it is designed to store well annotated data in a structured way. The ArrayExpress infrastructure consists of the database itself, data submissions in MAGE-ML format or via an online submission tool MIAMExpress, online database query interface, and the Expression Profiler online analysis tool. ArrayExpress accepts three types of submission, arrays, experiments and protocols, each of these is assigned an accession number. Help on data submission and annotation is provided by the curation team. The database can be queried on parameters such as author, laboratory, organism, experiment or array types. With an increasing number of organisations adopting MAGE-ML standard, the volume of submissions to ArrayExpress is increasing rapidly. The database can be accessed at http://www.ebi.ac.uk/arrayexpress.
