Sequence Family object

NAME

Bio::Cluster::SequenceFamily - Sequence Family object

SYNOPSIS

  use Bio::SeqIO;
  use Bio::Cluster::SequenceFamily;
  use File::Spec;
  my $file =  File::Spec->catfile('t','data','swiss.dat');
  my $seqio= Bio::SeqIO->new(-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.

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 : Bio::Cluster::SequenceFamily object

See Bio::Cluster::SequenceFamily.

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 : Bio::SimpleAlign

See 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 : Bio::SimpleAlign

See Bio::SimpleAlign

tree

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

See 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

members

 Title   : members
 Usage   : $members = $fam->members([$seq1,$seq1]);
 Function: Deprecated. Use add_members() or get_members() instead
