OpenHelix

A gene expression/molecular abundance repository and a curated, online resource for gene expression data

Tutorial and training materials by OpenHelix

Learn to use the Gene Expression Omnibus, or GEO, which is a valuable resource designed to store high-throughput gene expression and molecular abundance data. GEO acts as a repository for the data, and provides interfaces to search, retrieve, and display a wealth of information about genes in many species. This includes microarray data and many other high-throughput techniques. GEO is one of the many useful resources supported by the National Center for Biotechnology Information, or NCBI.

You'll learn:

  • efficient ways to query GEO for specific genes or experimental designs
  • how to navigate through GEO output displays to find the specific information you want
  • how to navigate GEO

More about the resource:

GEO can be browsed or queried in several ways, including basic searches, advanced searches, and using nucleotide sequences to begin a search. GEO contains information about platforms, data series, samples, and more. Analysis tools including clustering features are available. Learning to mine the GEO data will provide the researcher with copious amounts of information about their species, tissues, or genes of interest.
