forester.js

forester.js is a general suite for dealing with phylogenetic trees.

forester.js Example

This basic example shows how to parse a New Hampshire formatted String into to a object representing a phylogenetic tree. Followed by pre- and post-order traversal, and writing back to a New Hampshire formatted String.

Change './forester' to 'forester' if you use this code outside of this package

var forester = require('./forester').forester;

var newHampshireFormattedString = "(((a:1,b:1,c:1)N:2,(d:1,e:1)M:4)O:4,f:1)R:1;";
var phylogeneticTree = forester.parseNewHampshire(newHampshireFormattedString);

console.log('Pre-order traversal:');
forester.preOrderTraversalAll(forester.getTreeRoot(phylogeneticTree), function (n) {
    console.log(n.name + ':' + n.branch_length);
});

console.log('Post-order traversal:');
forester.postOrderTraversalAll(forester.getTreeRoot(phylogeneticTree), function (n) {
    console.log(n.name + ':' + n.branch_length);
});

console.log('In New Hampshire format:');
var nh = forester.toNewHampshire(phylogeneticTree);
console.log(nh);

Expected output:

Pre-order traversal:
R:1
f:1
O:4
M:4
e:1
d:1
N:2
c:1
b:1
a:1
Post-order traversal:
a:1
b:1
c:1
N:2
d:1
e:1
M:4
O:4
f:1
R:1
In New Hampshire format:
(((a:1,b:1,c:1)N:2,(d:1,e:1)M:4)O:4,f:1)R:1;
