NAME

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

CONTENTS

DESCRIPTION

This module turns a tree structure into tabular data organized as an adjacency list, i.e. child -> parent relationships. The table at least has the following columns: ’child’ and ’parent’. ’length’ is interpreted as branch length. Columns starting with ’node:’ are created for semantic annotations to the focal node, columns starting with ’branch:’ are created for the focal branch. Records are listed in pre-order, so that references to parent nodes can be resolved immediately. Consequently, the root is the first record, without a parent. Example:



 ((A:1,B:2)n1:3,C:4)n2:0;



Becomes (with an extra example annotation):



 child  parent  length  node:dcterms:identifier
 n2             0       35462
 n1     n2      3       34987
 A      n1      1       73843
 B      n1      2       98743
 C      n2      4       39847
