A public repository for microarray gene expression data at the EBI
Tutorial and training materials by OpenHelix
| Learn to use ArrayExpress, a resource for storage and sharing of gene expression and other microarray data. ArrayExpress provides interfaces that allow users to search for complete datasets, for gene expression profiles, and for differentially expressed genes. Data content can be downloaded in multiple ways. ArrayExpress is one of the core databases of EBI, the European Bioinformatics Institute, and it is a public archive for functional genomics data. | |||||
You'll learn:
- to query the archive of ArrayExpress for records of experiments, arrays, and protocols, and to export data
- to query for expression profiles of genes, and identify groups of genes with similar expression profiles
- to find conditions under which a gene is differentially expressed, and to find genes differentially expressed under certain conditions
More about the resource:
ArrayExpress is one of the largest international public repositories for microarray data supporting publications. It consists of three, closely integrated databases, plus data submission and analysis tools. Data are available for filtered browsing, for querying by accession numbers, gene names, a variety of experimental parameters, and by keywords. Entire datasets or selected subsets can be retrieved and exported into analysis programs. To facilitate sharing of information, and to provide access to high quality data, ArrayExpress has adopted the standards of the Microarray Gene Expression Data Society (MGED).
