i have a list of genes with their nc ids
is it posible to download the bulk list from refseq database
May be you can try NCBI Entrez http://www.ncbi.nlm.nih.gov/sites/batchentrez
Works pretty well, although with >10,000 entries you might be obliged to split queries (you might get a "bad gateway" error). My longest download consisted of slightly more than 5000 entries.
If you have access to refseq blast databases from NCBI then you can use blastdbcmd to extract the sequence (if that is what you are after).
Other option could be e-utilities from NCBI.
Sir, i tried this but its not working for me .
any other option to download bulk of NC ids
Can you be more specific about what is "not working"? Perhaps we can debug that part.
I have a list of NC ids of genes of interest , i want to download them into a single shot .
so that i dnt need to go for individually download
You had already said that in the original post. The blastdbcmd method should work in this case. If you tried to use that and ran into some problems then let us know what did not work with that method.
