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 will 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

Video Tip of the Week: Digital Expression Explorer for RNA-seq: Coming over my digital transom in a couple of different ways recently, the Digital Expression Explorer caught my attention. I have a soft spot for expression. It's the business end of what's going on, ...

Video Tip of the Week: My Cancer Genome: There are a lot of cancer database resources out there. Most of the ones we've focused on have been the data repository types. TCGA, ICGC, CaBIG, COSMIC, Cancer Genome Workbench, UCSC Cancer Genomic Br...

Tip of the Week: BioGPS for expression data and more: This week's tip introduces BioGPS, or Gene Portal System. We get a lot of questions about two things that BioGPS can help you to tackle: what do I do with a list of genes to find out what they are? An...

Tip of the Week: Data Downloading from Gene Expression Omnibus (GEO): There are times when being able to download the data used to create a publication is very useful. Perhaps you want to compare interesting data to some of your own. Or you may want to analyze the data d...
