[Genome] quick question about the version/release date of the annotations

[Archana Thakkapallayil]

Hello Wenzhong,

Assembly-specific track releases, updates, and release dates are noted 
in our Release Log at:
http://genome.ucsc.edu/goldenPath/releaseLog.html

The exact Ensembl release information is not given in the Release Log 
for hg18.  However, you could get this information by clicking into the 
track settings page for the Ensembl Gene track:
http://genome.ucsc.edu/cgi-bin/hgTrackUi?db=hg18&g=ensGene

The refSeq data is updated once per week, usually on Sunday. As 
mentioned in the README:
ftp://hgdownload.cse.ucsc.edu/goldenPath/hg18/bigZips/README.txt

For the hg18 assembly:
UCSC Genes: release date ( 6 April 2007 )
Ensembl Genes: Build 43
RefSeq Genes: last modified date ( 8 Jul 2007 )

I hope this information helps.  If you have any further questions, 
please do not hesitate to write back to this list.

Regards,

Archana
