NAME

DESCRIPTION

first line

the number of tips, the number of characters

subsequent lines

offspring name, parent name, branch length, character state(s).

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

 4 2
 A,n1,0.000000,1,2
 B,n1,0.000000,1,2
 n1,n2,0.000000
 C,n2,0.000000,2,2
 n2,n3,0.000000
 D,n3,0.000000,2,1

To the unparse() function pass a tree object as value of the '-phylo' argument. The tips in this tree must be linked to taxon objects, and the taxon objects must be linked to datum objects whose character state sequences are to be serialized.

During unparsing, the tree is randomly resolved, and branch lengths are formatted to %f floats (i.e. integers, decimal point, integers).

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