Description
This module seeks to provide a simple method for pushing sequence changes
back to a Sequence Database - which can be an SQL compliant database, a file
based database, AceDB, etc.
Methods
Methods description
Title : write_seq Usage : write_seq(\@updatedseqs, \@addedseqs, \@deadseqs) Function: updates sequences in first array, adds sequences in the second array, and removes sequences in the third array. Example : Returns : Args : arrays of sequence objects that must be obtained from Bio::DB::UpdateableSeqI. |
Title : _add_seq Usage : _add_seq($seq) Function: Adds a new sequence Example : Returns : will throw an exception if sequences accession number already exists Args : a new seq object - should have an accession number |
Title : _remove_seq Usage : _remove_seq($seq) Function: Removes an existing sequence Example : Returns : will throw an exception if sequence does not exists for the primary_id Args : a seq object that was retrieved from Bio::DB::UpdateableSeqI |
Title : _update_seq Usage : _update_seq($seq) Function: Updates a sequence Example : Returns : will throw an exception if sequence is out of sync from expected val. Args : a seq object that was retrieved from Bio::DB::UpdateableSeqI |

bioperl-l@bioperl.org
rather than to the module maintainer directly. Many experienced and
reponsive 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.
Report bugs to the Bioperl bug tracking system to help us keep track
the bugs and their resolution. Bug reports can be submitted via the

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
| Methods inheirited from Bio::DB::SeqI | Top |
Title : get_PrimarySeq_stream
Usage : $stream = get_PrimarySeq_stream
Function: Makes a Bio::DB::SeqStreamI compliant object
which provides a single method, next_primary_seq
Returns : Bio::DB::SeqStreamI
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
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
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
