What kinds of retrievals are possible in GEO?
There are several ways to retrieve GEO data. One way is by entering a valid GEO accession number in the Accession Display bar. Another is to browse the list of current GEO repository contents. All data are available for download from the GEO FTP site. Both simple and sophisticated searches of GEO data and linking to other Entrez databases can be accomplished using Entrez GEO Profiles and Entrez GEO DataSets. As with other NCBI Entrez databases (e.g., PubMed) a simple Boolean phrase may be entered and restricted to any number of supported attribute fields, enabling effective query and mining. Entrez GEO Profiles retrieves individual gene expression profiles, and Entrez GEO DataSets retrieves complete experiments. Please see the overview or recent publications for more information.
