[Bioperl-l] MSG: acc does not exist, but acc # is OK

[Arya Akmal]

Hello-

  I get the following exception thrown up if I try to retrieve _any_ 
GenBank sequence:

------------- EXCEPTION  -------------
MSG: acc does not exist
STACK Bio::DB::WebDBSeqI::get_Seq_by_acc 
/Library/Perl/5.8.1/Bio/DB/WebDBSeqI.pm:176
STACK toplevel test:47

--------------------------------------

  in response to something as trivial as:

  $gb = new Bio::DB::GenBank();
  $seq = $gb->get_Seq_by_acc('M29081');


I have no trouble with any of the other supported DBs (including 
RefSeq), but am consistently unable to retrieve anything using 
Bio::DB::GenBank.

I've seen previous postings to this list
  (http://bioperl.org/pipermail/bioperl-l/2004-February/014962.html)
on a similar problem, but I'm quite sure the accession numbers I'm 
trying are bona fide. I've tried many different accession numbers and 
IDs without success.

Has anyone seen this type of problem before?

thanks.
