Build Supertree Server

Select the Browse button to choose a tree file to upload. When you press the Build supertree button, this script a supertree (if one exists). The server uses one of three algorithms described in chapters by David Bryant, Philip Daniel, Charles Semple, and Mike Steel, in the forthcoming book on supertrees edited by Olaf Bininda-Emonds. Each algorithm outputs a supertree only if the input trees are compatible (they differ in the definition of "compatible").

Note: there is no error checking on the input!

Algorithm	Description
AncestralBuild	Less strict version of LabelledBuild
LabelledBuild	Supertree algorithm for fully labelled trees. Each node of the input treesw must be labelled, either with a taxon name or an arbitrary, unique label.
RankedTree	Supertree with dated ancestors. This algorithm requires ultrametric trees with branch lengths. It ranks the nodes based on the branch lengths.

Examples

Fully labelled trees for spiders (use for AncestralBuild or LabelledBuild)

When you press the Build supertree button, this script builds a supertree (if one exists).

You can view the result as a Postscript file, a PDF file, a Newick format tree description, and NEXUS tree file. You can also view the tree using Christian Zmasek's ATV applet.
