For details of public SRS servers, see the "Public SRS Installations" at:
http://bioblog.instem.com/download/srs-parser-and-software-downloads/public-srs-installations/
Current versions of EMBOSS come with a number of data sources configured
which are accessed via the data server support. You can see details of
the configured servers using the showserver command:
http://emboss.sourceforge.net/apps/release/6.6/emboss/apps/showserver.html
And you can access entries via these services by using the slightly
extended USA which specifies the server as well as the database, for
example:
entret -stdout -auto dbfetch:embl:L12345
to get EMBL-Bank data from dbfetch, or to get the same entry from NCBI
Entrez:
entret -stdout -auto entrez:nucleotide:L12345
Since NCBI's GenBank is part of the INSDC (http://www.insdc.org/), the
data in GenBank is also available in ENA EMBL-Bank and DDBJ. So you
could use the existing server definitions containing EMBL-Bank or DDBJ.
Alternatively you can define your own (see
http://emboss.open-bio.org/html/adm/ch04s01.html) to access GenBank via
NCBI's E-Utitlites (http://eutils.ncbi.nlm.nih.gov/), for example:
# NCBI GenBank+RefSeq via NCBI Entrez
DB nucleotide [
type: nucleotide
method: entrez
format: genbank
]
Since NCBI have also recently released command-line clients for their
E-Utilities Web Services
(http://www.ncbi.nlm.nih.gov/news/02-06-2014-entrez-direct-released/)
another option would be to use these directly or wrap them as EMBOSS
database definitions for your commonest queries.
All the best,
Hamish
