[Biopython] qblast against RefSeq

[Miguel Romero]

Hi!
Im learning how to run BLAST over the internet and Im interested in
blasting against the RefSeq database. For now I have managed to blast
against the nr database with:

result_handle = NCBIWWW.qblast("blastp", "nr", sequence_string)

but I dont know how to search against RefSeq, if I enter:

result_handle = NCBIWWW.qblast("blastp", "refseq", sequence_string)

the blast record is empty! Is it possible to blast against the RefSeq
database? What should I type in the second argument?

Thank you!

Miguel Romero
