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.
