NAME

Bio::Cluster::SequenceFamily - Sequence Family object

SYNOPSIS

use Bio::Cluster::SequenceFamily

use Bio::SeqIO;
use Bio::Cluster::SequenceFamily;

my $file =  Bio::Root::IO->catfile('t','data','swiss.dat');
my $seqio= new Bio::SeqIO('-format' => 'swiss',
                        '-file'   => $file);
my @mem;
while(my $seq = $seqio->next_seq){
  push @mem, $seq;
}

#create the family
my $family = Bio::Cluster::SequenceFamily->new(-family_id=>"Family_1",
                                               -description=>"Family Description Here",
                                               -annotation_score=>"100",
                                             -members=>\@mem);

#access the family

foreach my $mem ($family->get_members){
  print $mem->display_id."\t".$mem->desc."\n";
}

#select members if members have a Bio::Species Object

my @mem = $family->get_members(-binomial=>"Homo sapiens");
@mem = $family->get_members(-ncbi_taxid => 9606);
@mem = $family->get_members(-common_name=>"Human");
@mem = $family->get_members(-species=>"sapiens");
@mem = $family->get_members(-genus=>"Homo");

DESCRIPTION

This is a simple Family object that may hold any group of object. For more specific families, one should derive from FamilyI.

APPENDIX

The rest of the documentation details each of the object methods. Internal methods are usually preceded with a "_".

new

Title   : new
Usage   : my $family = Bio::Cluster::SequenceFamily->new(-family_id=>"Family_1",
                                      -description=>"Family Description Here",
                                      -annotation_score=>"100",
                                      -members=>\@mem);
Function: Constructor for SequenceFamily object
Returns : L<Bio::Cluster::SequenceFamily> object

version

Title   : version
Usage   : $family->version("1.0");
Function: get/set for version
Returns : a string version of the family generated.

annotation_score

Title   : annotation_score
Usage   : $family->annotation_score(100);
Function: get/set for annotation_score which
          represent the confidence in which the 
          consensus description has been assigned
          to the family.
Returns : L<Bio::SimpleAlign>

alignment

Title   : alignment
Usage   : $family->alignment($align);
Function: get/set for an alignment object representing
          the multiple alignment of the members of the family.
Returns : L<Bio::SimpleAlign>

tree

Title   : tree
Usage   : $family->tree($tree);
Function: get/set for an tree object representing
          the phylogenetic tree of the family. 
Returns : L<Bio::Tree>

Bio::Cluster::FamilyI methods

family_score

Title   : family_score
Usage   : Bio::Cluster::FamilyI->family_score(95);
Function: get/set for the score of algorithm used to generate
          the family if present

          This is aliased to cluster_score().

Returns : the score
Args    : the score

family_id

Title   : family_id
Usage   : $family->family_id("Family_1"); 
Function: get/set for family id 

          This is aliased to display_id().

Returns : a string specifying identifier of the family

Bio::ClusterI methods

display_id

Title   : display_id
Usage   : 
Function: Get/set the display name or identifier for the cluster
Returns : a string
Args    : optional, on set the display ID ( a string)

description

Title   : description
Usage   : $fam->description("POLYUBIQUITIN")
Function: get/set for the consensus description of the cluster
Returns : the description string 
Args    : Optional the description string

get_members

Title   : get_members
Usage   : Valid criteria:
          -common_name
          -binomial
          -ncbi_taxid
          -organelle
          -genus
          $family->get_members(-common_name =>"human");
