Mailing Lists
User feedback is an integral part of the evolution of this and other Bioperl modules. Send your comments and suggestions preferably to one of the Bioperl mailing lists. Your participation is much appreciated. bioperl-l@bioperl.org - General discussion http://bioperl.org/MailList.shtml - About the mailing lists

Reporting Bugs
Report bugs to the Bioperl bug tracking system to help us keep track the bugs and their resolution. Bug reports can be submitted via email or the web: bioperl-bugs@bio.perl.org http://bugzilla.bioperl.org/ Email birney@ebi.ac.uk Describe contact details here 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_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_PrimarySeq_stream
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

get_all_primary_ids
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 maybe 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

get_Seq_by_primary_id
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
