Hi Pete, The UCSC Genes process is somewhat complex, with mRNAs and ESTs contributing evidence to exons and introns, but not being used exclusively as evidence for a gene. The methods (which can be different for different assemblies, depending on when the track was made) are outlined on the description pages. To get to the methods, click on the blue "UCSC Genes" track name for the assembly you are looking at (for hg19, the page is: http://genome.ucsc.edu/cgi-bin/hgGene?hgg_do_kgMethod=1&db=hg19).
If you have already seen this page and you are asking for more specifics, please feel free to contact us again at [email protected]. -- Brooke Rhead UCSC Genome Bioinformatics Group On 10/25/10 09:48, Pete Shepard wrote: > Dear Genome Browser, > > I am wondering for your known genes track what is the requirement for a 3' > end.
