[Genome] [Fwd: UCSC knownGene database file]

[Hiram Clawson]

Good Afternoon Jeff:

You can read about the process for the current hg18 known gene
procedure in the details page for the known gene track:
	http://genome.ucsc.edu/cgi-bin/hgTrackUi?db=hg18&g=knownGene

And the previous procedure in the hg17 known gene track:
	http://genome.ucsc.edu/cgi-bin/hgTrackUi?db=hg17&g=knownGene

Note the "Methods" section on both of the pages.

Please refer your genome questions in the future to the genome email
alias which is copied on this email.
