| TVi help: phylogenetic tree data |
|
Phylogenetic trees are described using the commonly-used Newick format:
(B,(A,C,E),D); Leaf nodes are represented by a node ID; internal tree nodes correspond to pairs of matched parentheses. Optionally, branch lengths may be specified by putting a colon and a number after each node: (B:6.0,(A:5.0,C:3.0,E:4.0):5.0,D:11.0); |
