Downloading protein sequences for a set of gene IDs from NCBI.

Hi All,

I have around 5000 Gene IDs of a particular species. I would like to retrieve all protein sequences for those gene ID.

What I tried: 1) from NCBI ftp, we can get the protein sequences of a various species. 2) E-utility from NCBI. but not able to download.

Please help me.

sequence

Perhaps a slightly "brutal" approach, but I would just download everything for your species of interest and then filter the obtained data in command line. Since you are looking for 5000 proteins you are already looking for a big subset of all proteins...

Hi Sir,

Kindly let me know how to do it for 100 gene ID atleast.
