Map Viewer Genome Browser from NCBI

Tutorial and training materials by OpenHelix

Learn to use Map Viewer, a genome browser from the NCBI. Map Viewer organizes and displays dozens of species genomes, and provides additional context with appropriate annotations for the genomic sequences. Many levels of detail are provided for each genome. You have access to the organism homepage, the complete genome view, the map view of a selected region of interest and the sequence view presenting the sequencing data and annotation for a very specific genomic region. Add variation data, easily view homologs in many species, and more. Extensive integration with other NCBI tools enables researchers to link quickly to relevant additional details.

You'll learn:

  • to perform basic and advanced searches for discovery of information
  • to search a genome with a sequence using BLAST
  • to employ the Maps and Options features to customize your views
  • to utilize additional tools to find clones and jump to chromosomal regions
  • to utilize extensive links to other NCBI resources that may be helpful to your research

More about the resource:

Map Viewer is one of the numerous tools within the NCBI resources. First developed to organize and display a Drosophila genome in 2000, the Map Viewer has grown to contain dozens of species, including: vertebrates, invertebrates, protozoa, plants, and fungi. Map Viewer has mammalian and model species, but also has an excellent representation of non-mammalian species which can be difficult to find in other browsers. Many data types of maps can be examined, depending on the species.
