Gene Expression Omnibus Datasets (GDS) is a public functional genomics data repository supporting MIAME-compliant data submissions. Array- and sequence-based data are accepted. Tools are provided to help users query and download experiments and curated gene expression profiles.
The GEO DataSets database stores original submitter-supplied records (Series, Samples and Platforms) as well as curated DataSets. Curated DataSets form the basis of GEO's advanced data display and analysis features, including tools to identify differences in gene expression levels and cluster heatmaps.
