Does anyone know if there is a way to get a Taxonomy node and/or
taxonid from a gi number using the flatfile with taxonomy db?
I have blast output that I want to append taxonomic information to. I
have hundreds of thousands of items to do this for, so it's not
practical to use entrez to query the NCBI database.
I have the GI->taxid file from the taxonomy ftp but it's 3.2GB so I
think much too large to put into a hash!
This was also discussed in 2009:
http://bioperl.org/pipermail/bioperl-l/2009-April/029751.html but I
don't think there was a conclusion?
Thanks for your help
