experts will be able look at the problem and quickly address it. Please
include a thorough description of the problem with code and data examples if
at all possible.

The rest of the documentation details each of the object methods. Internal
methods are usually preceded with a _
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
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
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
Title : get_PrimarySeq_stream
Usage : $stream = get_PrimarySeq_stream
Function: Makes a Bio::SeqIO compliant object
which provides a single method, next_seq
Returns : Bio::SeqIO
Args : none
Title : get_all_ids
Usage : @ids = $seqdb->get_all_primary_ids()
Function: gives an array of all the primary_ids of the
sequence objects in the database. These
may be ids (display style) or accession numbers
or something else completely different - they
*are not* meaningful outside of this database
implementation.
Example :
Returns : an array of strings
Args : none
Title : get_Seq_by_primary_id
Usage : $seq = $db->get_Seq_by_primary_id($primary_id_string);
Function: Gets a Bio::Seq object by the primary id. The primary
id in these cases has to come from $db->get_all_primary_ids.
There is no other way to get (or guess) the primary_ids
in a database.
The other possibility is to get Bio::PrimarySeqI objects
via the get_PrimarySeq_stream and the primary_id field
on these objects are specified as the ids to use here.
Returns : A Bio::Seq object
Args : accession number (as a string)
Throws : "acc does not exist" exception
