I have a long list of GI and I want their accession number
3 answers
Get this file and parse out the gi/accession numbers you need: ftp://ftp.ncbi.nih.gov/gene/DATA/gene2accession.gz
Use NCBI's eutils. Something like this: http://eutils.ncbi.nlm.nih.gov/entrez/eutils/efetch.fcgi?db=nucleotide&rettype=acc&id=568815597
