Fitch-Margoliash and Least-Squares Distance Methods using fitch

Description

kfitch is fitch-Margoliash and Least-Squares Distance Methods utilizing "fitch" methods provided in PHYLIP web service.

Following block is a quotation from ffitch included in PHYLIPNEW package. Estimates phylogenies from distance matrix data under the "additive tree model" according to which the distances are expected to equal the sums of branch lengths between the species. Uses the Fitch-Margoliash criterion and some related least squares criteria, or the Minimum Evolution distance matrix method. Does not assume an evolutionary clock. This program will be useful with distances computed from molecular sequences, restriction sites or fragments distances, with 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:

http://bioportal.bic.nus.edu.sg/phylip/fitch.html

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. kfitchis thus an interface of "runFitch" 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://soap.g-language.org/kbws/ for more information.
