Does anyone have any suggestions for fast ways to retrieve multiple genbank records using a list of genbank ids/accessions? I am interested in getting the Taxonomic and/or Organism fields for a large set of queries. They are blast hits for environmental RNA so could come from a variety of sources. I have a large number of runs (like 20 x 500 ids) so submitting them on the website is not really an option.
I tried the Entrez eSearch software but that is pretty dang slow to submit and download queries, plus I don't want to hammer the NCBI servers any more than I need to.
I have the space to download GenBank if anyone knows of a way to format the files into a form that is quickly queried.
Any help or tips would be appreciated.
