[Genome] question for refFlat.txt in mm7

[Kayla Smith]

Xiangdong,

Rest assured, the sequence data for mm7 does not change. What does 
change are the annotations to it.  In particular, refFlat is part of the 
set of annotations which are subject to a process of nightly updates.  
Here is a link to our FAQ on the frequency of GenBank updates:  
http://genome.ucsc.edu/FAQ/FAQreleases#release6

You can check the submission state or status of a particular accession 
on the NCBI website:  
http://www.ncbi.nlm.nih.gov/entrez/query.fcgi?DB=pubmed

I hope this is helpful to you.  Please don't hesitate to contact us 
again if you have more questions.
