Hi all, I am trying to extract the RNA sequences for sheep (or Ovis aries) in Refseq ftp site. The right directory should be vertebrate_mammalian: ftp://ftp.ncbi.nlm.nih.gov/refseq/release/vertebrate_mammalian/ But there so many *rna* files there, all named with some numbers, like vertebrate_mammalian.154.rna.fna.gz, not sure which one is for my target species. Readme files don?t really help on this. does anyone knows how to locate the right file for a target species there? Heyi

Thanks Jim, for the hint. That?s even worse, I will have to download and work on all files now. Heyi -------------------------------------------- On Fri, 10/4/13, James W.

Hi Heyi, You could try the following link to the sheep sequencing consortium web site. You'll find links to gff files there with known and predicted mRNAs, together with the latest draft assembly of the sheep genome sequence (together with thousands of unmapped scaffolds and contigs .....) http://www.livestockgenomics.csiro.au/sheep/oar3.1.php Hope the helps.

Thanks Darin, That?s very useful too! -------------------------------------------- On Sat Oct 5, Darin Takemoto wrote: Hi Heyi, One way to get the Refseq RNA sequences for a given species is to look up the species in the Taxonomy DB of NCBI and click through to the details page for the species of interest (in the case of Ovis aries it is Taxonomy ID: 9940).
