kcontml

Function

Gene frequency and continuous character Maximum Likelihood using contml

Description

kcontml is gene frequency and continuous character Maximum Likelihood utilizing "contml" methods provided in PHYLIP web service.

Following block is a quotation from fcontml included in PHYLIPNEW package.

Estimates phylogenies from gene frequency data by maximum likelihood under a model in which all divergence is due to genetic drift in the absence of new mutations. Does not assume a molecular clock. An alternative method of analyzing this data is to compute Nei's genetic distance and use one of the distance matrix programs. This program can also do maximum likelihood analysis of continuous characters that evolve by a Brownian Motion model, but it assumes that the characters evolve at equal rates and in an uncorrelated fashion, so that it does not take into account the usual correlations of characters.

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/contml.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. kcontml is thus an interface of "runContml" 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.
