Bio::Phylo::Unparsers::Fasta - Serializer used by Bio::Phylo::IO, no serviceable parts inside
Definition lines for each FASTA records are either (first choice) created from the generic 'fasta_def_line' annotation which can be manipulated like so:
$datum->set_generic( 'fasta_def_line' => $line )
So you can retrieve it by calling:
my $line = $datum->get_generic('fasta_def_line');
Alternatively the name of the $datum is used, or, lacking that, the name of the associated taxon, if any.
There is a mailing list at https://groups.google.com/forum/#!forum/bio-phylo for any user or developer questions and discussions.
The fasta unparser is called by the Bio::Phylo::IO object. Look there to learn how to create phylip formatted files.
