Fitch-Margoliash method with contemporary tips using kitsch


kkitsch is fitch-Margoliash method with contemporary tips utilizing "kitsch" methods provided in PHYLIP web service.

Following block is a quotation from fkitsch included in PHYLIPNEW package. Estimates phylogenies from distance matrix data under the "ultrametric" model which is the same as the additive tree model except that an evolutionary clock is assumed. The Fitch-Margoliash criterion and other least squares criteria, or the Minimum Evolution criterion are possible. This program will be useful with distances computed from molecular sequences, restriction sites or fragments distances, with distances from DNA hybridization measurements, and with genetic distances computed from gene frequencies. PHYLIP web service is provided by National University of Singapore. Original web-service is located at the following URL:


This tools is a subset of Keio Bioinformatics Web Service (KBWS) package, which contains interfaces to bioinformatics web services through a proxy server at Keio University. kkitsch is thus an interface of "runKitsch" method included in KBWS SOAP service. This method can be alternatively accessed directly from programming languages as SOAP web service. Please refer to the KBWS online documentations http://www.g-language.org/kbws/ for more information.
