Bio::Phylo::Unparsers::Phylip - Serializer used by Bio::Phylo::IO, no serviceable parts inside

This module unparses a Bio::Phylo data structure into an input file for PHYLIP and RAxML. The file format (as it is interpreted here) consists of:

first line

the number of species, a space, the number of characters

subsequent lines

ten-character species name, sequence

Here is an example of what the output might look like:

 4 2
 Species_1 AC
 Species_2 AG
 Species_3 GT
 Species_4 GG

To the unparse() function pass a matrix object or a project (whose first matrix will be serialized) as value of the '-phylo' argument. After serialization, any shortened phylip-specific names (which need to be 10 characters long) will have been assigned to the 'phylip_name' slot of set_generic. Example:

 my $phylip_string = unparse(
 	-format => 'phylip',
 	-phylo  => $matrix,
 );
 for my $seq ( @{ $matrix->get_entities } ) {
    # this returns the shortened name, which is unique to the matrix
 	my $phylip_name = $seq->get_generic('phylip_name');
 }

The phylip module is called by the Bio::Phylo::IO object, so look there to learn about parsing and serializing in general.
