NAME¶
Bio::Cluster::UniGene - UniGene object
SYNOPSIS¶
use Bio::Cluster::UniGene;
use Bio::ClusterIO;
$stream = Bio::ClusterIO->new('-file' => "Hs.data",
'-format' => "unigene");
# note: we quote -format to keep older perl's from complaining.
while ( my $in = $stream->next_cluster() ) {
print $in->unigene_id() . "\n";
while ( my $sequence = $in->next_seq() ) {
print $sequence->accession_number() . "\n";
}
}
DESCRIPTION¶
This UniGene object implements the Bio::Cluster::UniGeneI interface for the
representation if UniGene clusters in Bioperl. It is returned by the
Bio::ClusterIO parser for unigene format and contains all the data associated
with one UniGene record.
This class implements several interfaces and hence can be used wherever
instances of such interfaces are expected. In particular, the interfaces are
Bio::ClusterI as the base interface for all cluster representations, and in
addition Bio::IdentifiableI and Bio::DescribableI.
The following lists the UniGene specific methods that are available (see below
for details). Be aware next_XXX iterators take a snapshot of the array
property when they are first called, and this snapshot is not reset until the
iterator is exhausted. Hence, once called you need to exhaust the iterator to
see any changes that have been made to the property in the meantime. You will
usually want to use the non-iterator equivalents and loop over the elements
yourself.

size¶
Title : size
Usage : Bio::ClusterI->size();
Function: get for the size of the family,
calculated from the number of members
This is aliased to scount().
Returns : the size of the cluster
Args :
cluster_score¶
Title : cluster_score
Usage : $cluster ->cluster_score(100);
Function: get/set for cluster_score which
represent the score in which the clustering
algorithm assigns to this cluster.
For UniGene clusters, there really is no cluster score that
would come with the data. However, we provide an
implementation here so that you can score UniGene clusters
if you want to.
Returns : a number
Args : optionally, on set a number
get_members¶
Title : get_members
Usage : Bio::ClusterI->get_members(($seq1, $seq2));
Function: retrieve the members of the family by some criteria
Will return all members if no criteria are provided.
At this time this implementation does not support
specifying criteria and will always return all members.

Args :
Annotatable view at the object properties¶
annotation¶
Title : annotation
Usage : $obj->annotation($newval)
Function: Get/set the L<Bio::AnnotationCollectionI> object for
this UniGene cluster.
Many attributes of this class are actually stored within
the annotation collection object as L<Bio::AnnotationI>
compliant objects, so you can conveniently access them
through the same interface as you would e.g. access
L<Bio::SeqI> annotation properties.
If you call this method in set mode and replace the
annotation collection with another one you should know
exactly what you are doing.
Example :
Returns : a L<Bio::AnnotationCollectionI> compliant object
Args : on set, new value (a L<Bio::AnnotationCollectionI>
compliant object or undef, optional)
Implementation specific methods¶
These are mostly for adding/removing to array properties, and for
methods with special functionality.
add_member¶
Title : add_member
Usage :
Function: Adds a member object to the list of members.
Example :
Returns : TRUE if the new member was successfuly added, and FALSE
otherwise.
Args : The member to add.
remove_members¶
Title : remove_members
Usage :
Function: Remove the list of members for this cluster such that the
member list is undefined afterwards (as opposed to zero members).
Example :
Returns : the previous list of members
Args : none
next_locuslink¶
Title : next_locuslink
Usage : next_locuslink();
Function: Returns the next locuslink from an array referred
to using $obj->{'locuslink'}
If you call this iterator again after it returned undef, it
will re-cycle through the list of elements. Changes in the
underlying array property while you loop over this iterator
will not be reflected until you exhaust the iterator.
Example : while ( my $locuslink = $in->next_locuslink() ) {
print "$locuslink\n";
}
Returns : String
Args : None
next_express¶
Title : next_express
Usage : next_express();
Function: Returns the next tissue from an array referred
to using $obj->{'express'}
If you call this iterator again after it returned undef, it
will re-cycle through the list of elements. Changes in the
underlying array property while you loop over this iterator
will not be reflected until you exhaust the iterator.

print "$express\n";
}
Returns : String
Args : None
next_chromosome¶
Title : next_chromosome
Usage : next_chromosome();
Function: Returns the next chromosome line from an array referred
to using $obj->{'chromosome'}
If you call this iterator again after it returned undef, it
will re-cycle through the list of elements. Changes in the
underlying array property while you loop over this iterator
will not be reflected until you exhaust the iterator.
Example : while ( my $chromosome = $in->next_chromosome() ) {
print "$chromosome\n";
}
Returns : String
Args : None
next_protsim¶
Title : next_protsim
Usage : next_protsim();
Function: Returns the next protsim line from an array referred
to using $obj->{'protsim'}

print "$protsim\n";
}
Returns : String
Args : None
next_sts¶
Title : next_sts
Usage : next_sts();
Function: Returns the next sts line from an array referred
to using $obj->{'sts'}
If you call this iterator again after it returned undef, it
will re-cycle through the list of elements. Changes in the
underlying array property while you loop over this iterator
will not be reflected until you exhaust the iterator.
Example : while ( my $sts = $in->next_sts() ) {
print "$sts\n";
}
Returns : String
Args : None
next_txmap¶
Title : next_txmap
Usage : next_txmap();
Function: Returns the next txmap line from an array
referred to using $obj->{'txmap'}
If you call this iterator again after it returned undef, it
will re-cycle through the list of elements. Changes in the
underlying array property while you loop over this iterator
will not be reflected until you exhaust the iterator.
Example : while ( my $tsmap = $in->next_txmap() ) {
print "$txmap\n";
}
Returns : String
Args : None
Bio::IdentifiableI methods¶
object_id¶
Title : object_id
Usage : $string = $obj->object_id()
Function: a string which represents the stable primary identifier
in this namespace of this object. For DNA sequences this
is its accession_number, similarly for protein sequences
This is aliased to unigene_id().
Returns : A scalar
version¶
Title : version
Usage : $version = $obj->version()
Function: a number which differentiates between versions of
the same object. Higher numbers are considered to be
later and more relevant, but a single object described
the same identifier should represent the same concept
Unigene clusters usually won't have a version, so this
will be mostly undefined.
Returns : A number
Args : on set, new value (a scalar or undef, optional)
authority¶
Title : authority
Usage : $authority = $obj->authority()
Function: a string which represents the organisation which
granted the namespace, written as the DNS name for
organisation (eg, wormbase.org)
Returns : A scalar
Args : on set, new value (a scalar or undef, optional)
namespace¶
Title : namespace
Usage : $string = $obj->namespace()
Function: A string representing the name space this identifier
is valid in, often the database name or the name
describing the collection
Returns : A scalar
Args : on set, new value (a scalar or undef, optional)
Bio::DescribableI methods¶
display_name¶
Title : display_name
Usage : $string = $obj->display_name()
Function: A string which is what should be displayed to the user
the string should have no spaces (ideally, though a cautious
user of this interface would not assumme this) and should be
less than thirty characters (though again, double checking
this is a good idea)
This is aliased to unigene_id().
Returns : A scalar
Status : Virtual
description()¶
Title : description
Usage : $string = $obj->description()
Function: A text string suitable for displaying to the user a
description. This string is likely to have spaces, but
should not have any newlines or formatting - just plain
text. The string should not be greater than 255 characters
and clients can feel justified at truncating strings at 255
characters for the purposes of display
This is already demanded by Bio::ClusterI and hence is
present anyway.
Returns : A scalar
Bio::Factory::SequenceStreamI methods¶
next_seq¶
Title : next_seq
Usage : next_seq();
Function: Returns the next seq as a Seq object as defined by
$seq->sequence_factory(),
at present an empty Bio::Seq::RichSeq object with
just the accession_number() and pid() set
This iterator will not exhaust the array of member
sequences. If you call next_seq() again after it returned
undef, it will re-cycle through the list of member
sequences.
Example : while ( my $sequence = $in->next_seq() ) {
print $sequence->accession_number() . "\n";
}
Returns : Bio::PrimarySeqI object
Args : None
sequence_factory¶
Title : sequence_factory
Usage : $seqio->sequence_factory($seqfactory)
Function: Get/Set the Bio::Factory::SequenceFactoryI
Returns : Bio::Factory::SequenceFactoryI
Args : [optional] Bio::Factory::SequenceFactoryI
Private methods¶

Args : annotation key (a string)
on set, reference to an array holding the values
_annotation_dblink¶
Title : _annotation_dblink
Usage :

Args : annotation key (a string)
dbname (a string) (optional on get, mandatory on set)
on set, accession or ID (a string), and version
