Download Oldest release of Refseq

Question

[chochart]

Hi everyone,

I would like to know if it's possible to download an oldest release (especially release_50 of 2011) of Refseq NCBI db for virus, bacteria and archaea?

In fact I would like to perform a SEED annotation locally but SEED is out of date from 2011. I have a file who links old refrefseq with SEEDrole but many old reference have no link with the newest.

Thx.

Columns:

I would recommend that you first extract the target GIs from the current release, and subsequently fetch the missing records with Entrez Direct.

Thx for the answer but I already do that. I would like to know just if it possible to download directly the release of interest that I could have been certainly faster.
