• Linking to the Genome Browser from another software application
• The hgsid parameter

Question:
"How do I construct a hyperlink to the Genome Browser from my software?"

Response:
Link to the Genome Browser using a URL of the form:

http://archaea.ucsc.edu/cgi-bin/hgTracks?org=[org]&db=[db]&position=[position].

• org - specifies the genome in which you're interested. This parameter defaults to the latest Genome Browser version for that species.
• db - designates a specific assembly version. For example, to refer to the Feb 2002 release of Pyrococcus furiosus, you would use db=pyrFur2. The db parameter takes precedence over the org parameter.
• position - can be any search value valid for the genome specified by org.

Question:
"What is the hgsid parameter? Should I include it in URLs that link to the Genome Browser?"

Response:
The hgsid parameter is a temporary internally-used parameter that should not be used when constructing links to the Genome Browser.
