Become aware of genome browser resources with this introductory tutorial. Genome browsers organize tremendous volumes of genome sequence data, adding context to genomic sequence with many types of annotations. Several major genome web browsers are widely used to search, retrieve, and display genome information for human and numerous other species. Here we introduce Ensembl, Map Viewer, UCSC Genome Browser, and the Integrated Microbial Genomes (IMG) browser. We also introduce the GBrowse software system, which is the framework for many additional genome browsers. Biomedical researchers need to be aware of these resources and be able to access the data available within.

You will learn:

  • where to find these useful tools
  • an overview of the organization and display features
  • some guidance on how or why to choose a given browser for your research needs
