You may browse to the default genome position of an assembly when clicking the "submit"
button or you may specify a genome position in a variety of formats.
Valid position queries can include:
- Chromosome numbers
- Chromosomal coordinate ranges
- Gene names
- Accession numbers
- An mRNA, EST or STS marker
- Keywords from the Genbank description of an mRNA
To specify a genome position:
- Select the desired clade, genome and assembly
- Enter the desired query in the "search term" box (see sample queries below)
- Click the "submit" button
Note: A query may have multiple results. If this is the case, a results page will appear
listing each result along with the track it is associated with. Once selected, the result will
be displayed in the Browser with a highlighted tag, making it easier to identify.
Sample Queries
Below is a list of examples that might be used to query the Genome Browser. Note that not every query
listed here will produce a result in every assembly. The list serves only to illustrate the different
types of queries that can be performed.

Use this last format for author queries. Although Genbank requires the search format Evans JE,
internally it uses the format Evans,J.E.
