Helllo, The UCSC Genes process contains several layers of data from multiple sources (primary table = knownGene). The best place to read about this is the track description page. To view this, go into the assembly and click on the track name. Links to source tables, sub-tracks, methods, credits, etc. are all included. For any specific gene, click on the gene's name and examine the gene detail page for the specific evidence used for that transcript.
The RefSeq Genes track is based on the NCBI release. Again, the track and gene description pages may be helpful. The RefSeq Genes track is a subset of the UCSC Genes track (at the date of the UCSC Genes track creation). Hopefully this helps, Jennifer ------------------------------------------------ Jennifer Jackson UCSC Genome Bioinformatics Group ----- "Yuxin Li" <[email protected]> wrote: > From: "Yuxin Li" <[email protected]> > To: [email protected] > Sent: Wednesday, October 7, 2009 2:03:01 AM GMT -08:00 US/Canada Pacific > Subject: [Genome] Data source for the knownGene.txt annotation items > > Dear all, > > I am using the hg18 human genome and I noted that the genome > annotation file > knownGene.txt is distinctive from the refGene.txt.
