Supertree Estimation Datasets


This page contains datasets that may be useful for testing supertree methods, which combine a set of phylogenies into a single estimated phylogeny on the intersection of the taxa appearing in the input set [16]. In addition to sets of supertree inputs, the simulated datasets contain model (true) trees that can be used to assess supertrees' accuracy. Assessing accuracy on empirical datasets, however, is somewhat problematic [2]. If you would like to contribute benchmarks to this resource, please email tandy@cs.utexas.edu.

Simulated Data

SMIDGen: SMIDGen is a methodology for generating simulated datasets suitable as inputs to supertree methods. The data generation process mirrors data collection processes used by systematists when gathering empirical data, including creation of densely-sampled clade-based trees as well as sparsely-sampled scaffold trees.
