How to: Display genomic annotation graphically

Starting with...

A NUCLEOTIDE RECORD (e.g. NC_000001)

  1. Select the sequence you want to display from the nucleotide database (e.g. NC_000001).
  2. Click on Graphics to generate a diagram of the annotation in the graphical sequence viewer, as shown here.
  3. To find a gene or sequence of interest:
    1. Click on Tools, then Search.
    2. Enter a search term, such as a gene name, a descriptive word like kinase, or even a sequence.
    3. Select the desired result to have it displayed in the viewer.
    4. To further adjust the display, use the Configure menu.

Please note that there is a YouTube video video showing how to do this, as well as a Sequence Viewer homepage with lots of links to helpful information.


THE MAP VIEWER HOMEPAGE

  1. Beginning on the Map Viewer home page, select a genome. You may need to expand a section header to display the listing of organisms for some taxonomic groups.
  2. Click on the magnifying glass icon to open the main search page for this organism and enter your search or click on a chromosome to open a default display.
  3. Alternatively, enter your search using the search boxes in the section at the left and then review the search results.
  4. Use the Maps & Options dialog box to change displayed maps and/or refine the region shown.

Please note that there is a detailed MapViewer Help document available.


Gene, dbSNP, dbVar, GEO, Epigenomics, PheGenI AND OTHER RESOURCES

Many web sites at NCBI embed the graphical sequence viewer mentioned above.  Here is an example of how to access and use this tool from the Gene database:

  1. From the NCBI homepage, click on the search pull-down menu to select the Gene database.
  2. Type the gene name in the textbox and click Go. (See the Gene Help document for tips on searching this database.)
  3. Locate the desired Gene record in the results and click the gene symbol to open the record.
  4. Go to the section "Genomic regions, transcripts, and products" to see the Gene database's graphical sequence viewer display.
