BLASTing a limited database - help please :) (May/10/2011 )

Hi all

I have nucleotide sequences which I would like to BLAST, however I would not like to BLAST the whole database, instead just a selected series of sequences. I would like to know how to get around that. Can I limit my search to only include some accession numbers?

Thank you so much

You've to create an another DB with your subset sequences ( with formatdb )

and then blast your sequences against
