Description
Computes the least common ancestor of a group of nodes in a tree. The tree must be specified in the Rich Newick Format.
Usage
LCA tree_ident ({taxon1, taxon2, [, taxon3...]} [{taxon4, taxon5, [, taxon6...]}]) [result output file]
tree_ident |
The name of the network to analyse. |
mandatory |
({taxon1, taxon2, [, taxon3...]} [,{taxon4, taxon5, [, taxon6...]}]) |
A list of sets of taxa in the specified tree. |
mandatory |
result output file |
Optional file destination for command output. |
optional |
The tool prints the given tree with all internal nodes labeled. If a node is not labeled in the original tree, then the node receives a generated name. Then the tool reads sets of nodes. For each node set read, the command prints their least common ancestor.

Tree tree1 = ((1,4,3),2);
Tree tree2 = ((1,2),(4,3));
END;
BEGIN PHYLONET;
