With EMBOSS you can refer to sequences in the file:

filename:id

You can also put a list of these into a file, and use that with
@listfilename

But this can be slow - it will read the file for each ID. You can also
index the file with dbxfasta (or dbifasta) as a private database then
define a database in your .embossrc file and use the dbname:id syntax
(again you can use a list file, but it will be much faster)

Hope this helps. If you need more help setting up please ask again!
