A set of integrated tools to process tree data ready for supertree construction.

The STK is a handy box of tools to aid processing of data ready for analysis in programs like PAUP and TNT. It implements the supertree processing protocol proposed by Davis and Hill, 2008 (

The software was described in this paper in Biodiversity Data Journal:

The aim is to produce a GUI, web-based and command line interface for curating, processing and storing data ready for supertree analysis, all with common functionality. Our data format is a XML file that contains the trees and associated metadata for each tree.
