Bio::Cluster::UniGene - UniGene object
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";
}
}
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.
new() - standard new call
unigene_id() - set/get unigene_id
title() - set/get title (description)
gene() - set/get gene
cytoband() - set/get cytoband
mgi() - set/get mgi
locuslink() - set/get locuslink
homol() - set/get homologene
gnm_terminus() - set/get gnm_terminus
scount() - set/get scount
express() - set/get express, currently takes/returns a reference to an array of expressed tissues
next_express() - returns the next tissue expression from the expressed tissue array
chromosome() - set/get chromosome, currently takes/returns a reference to an array of chromosome lines
next_chromosome() - returns the next chromosome line from the array of chromosome lines
sts() - set/get sts, currently takes/returns a reference to an array of sts lines
next_sts() - returns the next sts line from the array of sts lines
txmap() - set/get txmap, currently takes/returns a reference to an array of txmap lines
next_txmap() - returns the next txmap line from the array of txmap lines
protsim() - set/get protsim, currently takes/returns a reference to an array of protsim lines
next_protsim() - returns the next protsim line from the array of protsim lines
sequences() - set/get sequence, currently takes/returns a reference to an array of references to seq info
next_seq() - returns a Seq object that currently only contains an accession number
This class implementes the following interfaces.

This should really only be used by ClusterIO, not directly
Returns : An array reference
Args : None or an array reference
Title : sequences
Usage : sequences();
Function: Returns or stores a reference to an array containing
sequence data.
This is mostly reserved for ClusterIO parsers. You should
use get_members() for get and add_member()/remove_members()
for set.
Returns : An array reference, or undef
Args : None or an array reference or undef
Title : species

This is aliased to unigene_id().
Returns : a string
Args : optional, on set the display ID ( a string)
Title : description

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 :
Title : cluster_score Usage : $cluster ->cluster_score(100); Function: get/set for cluster_score which represent the score in which the clustering algorithm assigns to this cluster. For UniGene clusters, there really is no cluster score that would come with the data. However, we provide an implementation here so that you can score UniGene clusters if you want to. Returns : a number Args : optionally, on set a number
Title : get_members
Usage : Bio::ClusterI->get_members(($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.
Returns : the array of members
Args :
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)
These are mostly for adding/removing to array properties, and for methods with special functionality.
Title : add_member
Usage :
Function: Adds a member object to the list of members.
Example :
Returns : TRUE if the new member was successfully added, and FALSE
otherwise.
Args : The member to add.
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
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
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.
Example : while ( my $express = $in->next_express() ) {
print "$express\n";
}
Returns : String
Args : None
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
Title : next_protsim
Usage : next_protsim();
Function: Returns the next protsim line from an array referred
to using $obj->{'protsim'}
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 $protsim = $in->next_protsim() ) {
print "$protsim\n";
}
Returns : String
Args : None
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
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
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
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)
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)
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)
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 assume 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
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
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
Title : sequence_factory Usage : $seqio->sequence_factory($seqfactory) Function: Get/Set the Bio::Factory::SequenceFactoryI Returns : Bio::Factory::SequenceFactoryI Args : [optional] Bio::Factory::SequenceFactoryI
Title : _annotation_value
Usage :
Function: Private method.
Example :
Returns : the value (a string)
Args : annotation key (a string)
on set, annotation value (a string)
Title : _annotation_value_ary
Usage :
Function: Private method.
Example :
Returns : reference to the array of values
Args : annotation key (a string)
on set, reference to an array holding the values
Title : _annotation_dblink
Usage :
Function: Private method.
Example :
Returns : array of accessions for the given database (namespace)
Args : annotation key (a string)
dbname (a string) (optional on get, mandatory on set)
on set, accession or ID (a string), and version
Title : _remove_dblink
Usage :
Function: Private method.
Example :
Returns : array of accessions for the given database (namespace)
Args : annotation key (a string)
dbname (a string) (optional)
