Bio::Species - Generic species object


    $species = Bio::Species->new(-classification => [@classification]);
                                    # Can also pass classification
                                    # array to new as below

    $species->classification(qw( sapiens Homo Hominidae
                                 Catarrhini Primates Eutheria
                                 Mammalia Vertebrata Chordata
                                 Metazoa Eukaryota ));

    $genus = $species->genus();

    $bi = $species->binomial();     # $bi is now "Homo sapiens"

    # For storing common name

    # For storing subspecies


Provides a very simple object for storing phylogenetic information. The classification is stored in an array, which is a list of nodes in a phylogenetic tree. Access to getting and setting species and genus is provided, but not to any of the other node types (eg: "phylum", "class", "order", "family"). There's plenty of scope for making the model more sophisticated, if this is ever needed.

A methods are also provided for storing common names, and subspecies.

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


 Title   : new
 Usage   : my $obj = Bio::Species->new(-classification => \@class)
 Function: Build a new Species object
 Returns : Bio::Species object
 Args    : -ncbi_taxid     => NCBI taxonomic ID (optional)
           -classification => arrayref of classification


 Title   : classification
 Usage   : $self->classification(@class_array);
           @classification = $self->classification();
 Function: Get/set the lineage of this species. The array provided must be in
           the order ... ---> SPECIES, GENUS ---> KINGDOM ---> etc.
 Example : $obj->classification(qw( 'Homo sapiens' Homo Hominidae
           Catarrhini Primates Eutheria Mammalia Vertebrata
           Chordata Metazoa Eukaryota));
 Returns : Classification array
 Args    : Classification array 
           A reference to the classification array. In the latter case
           if there is a second argument and it evaluates to true,
           names will not be validated. NB: in any case, names are never
           validated anyway.


 Title   : ncbi_taxid
 Usage   : $obj->ncbi_taxid($newval)
 Function: Get/set the NCBI Taxon ID
 Returns : the NCBI Taxon ID as a string
 Args    : newvalue to set or undef to unset (optional)


 Title   : common_name
 Usage   : $self->common_name( $common_name );
           $common_name = $self->common_name();
 Function: Get or set the common name of the species
 Example : $self->common_name('human')
 Returns : The common name in a string
 Args    : String, which is the common name (optional)


 Title   : division
 Usage   : $obj->division($newval)
 Function: Genbank Division for a species
 Returns : value of division (a scalar)
 Args    : value of division (a scalar)


 Title   : species
 Usage   : $self->species( $species );
           $species = $self->species();
 Function: Get or set the scientific species name.
 Example : $self->species('Homo sapiens');
 Returns : Scientific species name as string
 Args    : Scientific species name as string


 Title   : genus
 Usage   : $self->genus( $genus );
           $genus = $self->genus();
 Function: Get or set the scientific genus name.
 Example : $self->genus('Homo');
 Returns : Scientific genus name as string
 Args    : Scientific genus name as string


 Title   : sub_species
 Usage   : $obj->sub_species($newval)
 Function: Get or set the scientific subspecies name.
 Returns : value of sub_species
 Args    : newvalue (optional)


 Title   : variant
 Usage   : $obj->variant($newval)
 Function: Get/set variant information for this species object (strain,
           isolate, etc).
 Example : 
 Returns : value of variant (a scalar)
 Args    : new value (a scalar or undef, optional)


 Title   : binomial
 Usage   : $binomial = $self->binomial();
           $binomial = $self->binomial('FULL');
 Function: Returns a string "Genus species", or "Genus species subspecies",
           if the first argument is 'FULL' (and the species has a subspecies).
 Args    : Optionally the string 'FULL' to get the full name including
           the subspecies.


 Title   : validate_species_name
 Usage   : $result = $self->validate_species_name($string);
 Function: Validate the species portion of the binomial
 Args    : string
 Notes   : The string following the "genus name" in the NCBI binomial
           is so variable that it's not clear that this is a useful
           function. Consider the binomials 
           "Simian 11 rotavirus (serotype 3 / strain SA11-Patton)",
           or "St. Thomas 3 rotavirus", straight from GenBank.
           This is particularly problematic in microbes and viruses.
           As such, this isn't actually used automatically by any Bio::Species


 Title   : organelle
 Usage   : $self->organelle( $organelle );
           $organelle = $self->organelle();
 Function: Get or set the organelle name
 Example : $self->organelle('Chloroplast')
 Returns : The organelle name in a string
 Args    : String, which is the organelle name
