NAME

Bio::DB::XEMBL - Database object interface for XEMBL entry retrieval

SYNOPSIS

 use Bio::DB::XEMBL;

 $embl = new Bio::DB::XEMBL;

 # remember that XEMBL_ID does not equal GenBank_ID!
 $seq = $embl->get_Seq_by_id('BUM'); # EMBL ID
	print "cloneid is ", $seq->id, "\n";

 # or changeing to accession number and Fasta format ...
 $seq = $embl->get_Seq_by_acc('J02231'); # XEMBL ACC
	print "cloneid is ", $seq->id, "\n";

 # especially when using versions, you better be prepared
 # in not getting what what want
 eval {
     $seq = $embl->get_Seq_by_version('J02231.1'); # XEMBL VERSION
 }
 print "cloneid is ", $seq->id, "\n" unless $@;

 my $seqio = $embl->get_Stream_by_batch(['U83300','U83301','U83302']);
 while( my $clone =  $seqio->next_seq ) {
	print "cloneid is ", $clone->id, "\n";
 }

DESCRIPTION

Allows the dynamic retrieval of Bio::Seq objects from the XEMBL database. See Bio::Seq for details.

APPENDIX

The rest of the documentation details each of the object methods. Internal methods are usually preceded with a _

get_Seq_by_id

Title   : get_Seq_by_id
Usage   : $seq = $db->get_Seq_by_id('ROA1_HUMAN')
Function: Gets a Bio::Seq object by its name
Returns : a Bio::Seq object
Args    : the id (as a string) of a sequence
Throws  : "id does not exist" exception

get_Stream_by_batch

Title   : get_Stream_by_batch
Usage   : $seq = $db->get_Stream_by_batch($ref);
Function: Retrieves Seq objects from XEMBL 'en masse', rather than one
          at a time. Currently this is not particularly efficient, as
          it loads the entire result into memory and parses it.
Example :
Returns : a Bio::SeqIO stream object
Args    : $ref : an array reference containing a list of unique 
          ids/accession numbers.

get_Seq_by_acc

Title   : get_Seq_by_acc
Usage   : $seq = $db->get_Seq_by_acc('X77802');
Function: Gets a Bio::Seq object by accession number
Returns : A Bio::Seq object
Args    : accession number (as a string)
Throws  : "acc does not exist" exception

get_Seq_by_version

Title   : get_Seq_by_version
Usage   : $seq = $db->get_Seq_by_version('X77802.1');
Function: Gets a Bio::Seq object by sequence version
Returns : A Bio::Seq object
Args    : accession.version (as a string)
Throws  : "acc.version does not exist" exception
