NAME

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

DESCRIPTION

This module turns a tree object into a newick formatted (parenthetical) tree description. It is called by the Bio::Phylo::IO facade, don't call it directly. You can pass the following additional arguments to the unparse call:

# by default, names for tips are derived from $node->get_name, if 
# 'internal' is specified, uses $node->get_internal_name, if 'taxon'
# uses $node->get_taxon->get_name, if 'taxon_internal' uses 
# $node->get_taxon->get_internal_name, if $key, uses $node->get_generic($key)
-tipnames => one of (internal|taxon|taxon_internal|$key)

# for things like a translate table in nexus, or to specify truncated
# 10-character names, you can pass a translate mapping as a hashref.
# to generate the translated names, the strings obtained following the
# -tipnames rules are used.
-translate => { Homo_sapiens => 1, Pan_paniscus => 2 }	

# array ref used to specify keys, which are embedded as key/value pairs (where
# the value is obtained from $node->get_generic($key)) in comments, 
# formatted depending on '-nhxstyle', which could be 'nhx' (default), i.e.
# [&&NHX:$key1=$value1:$key2=$value2] or 'mesquite', i.e. 
# [% $key1 = $value1, $key2 = $value2 ]
-nhxkeys => [ $key1, $key2 ]	

# if set, appends labels to internal nodes (names obtained from the same
# source as specified by '-tipnames')
-nodelabels => 1

# specifies a formatting style / dialect
-nhxstyle => one of (mesquite|nhx)

# specifies a branch length sprintf number formatting template, default is %f
-blformat => '%e'
