Maximum Likelihood Analysen

Background

Software

  • PAML (for Phylogenetic Analysis by Maximum Likelihood)
    • Comparison and tests of phylogenetic trees
    • Estimation of parameters in sophisticated substitution models, including models of variable rates among sites and models for combined analysis of multiple genes or site partitions
    • Likelihood ratio tests of hypotheses through comparison of implemented models
    • Estimation of divergence times under global and local clock models
    • Likelihood (Empirical Bayes) reconstruction of ancestral sequences using nucleotide, amino acid and codon models
    • Generation of datasets of nucleotide, codon, and amino acid sequence by Monte Carlo
      simulation
    • Estimation of synonymous and nonsynonymous substitution rates and detection of positive
      selection in protein-coding DNA sequences
    • Bayesian estimation of species divergence times incorporating uncertainties in fossil calibration

Bayesian Analysis

Background

Software

  • BEAST - Bayesian Evolutionary Analysis Sampling Trees
    Description: "BEAST is a cross-platform program for Bayesian analysis of molecular sequences using MCMC. It is entirely orientated towards rooted, time-measured phylogenies inferred using strict or relaxed molecular clock models. It can be used as a method of reconstructing phylogenies but is also a framework for testing evolutionary hypotheses without conditioning on a single tree topology. BEAST uses MCMC to average over tree space, so that each tree is weighted proportional to its posterior probability. We include a simple to use user-interface program for setting up standard analyses and a suit of programs for analysing the results."

  • MrBayes - Bayesian Inference of Phylogeny
    Description: "MrBayes is a program for Bayesian inference and model choice across a wide range of phylogenetic and evolutionary models. MrBayes uses Markov chain Monte Carlo (MCMC) methods to estimate the posterior distribution of model parameters."

Phylogenetic Networks

Background

 

Software

  • Splits Tree
    • Homepage: http://www.splitstree.org/
    • Publication: Huson, D. H., & Bryant, D. (2006). Application of phylogenetic networks in evolutionary studies. Molecular Biology and Evolution, 23(2), 254–67. http://doi.org/10.1093/molbev/msj030
    • SplitsTree4 is the leading application for computing unrooted phylogenetic networks from molecular sequence data. Given an alignment of sequences, a distance matrix or a set of trees, the program will compute a phylogenetic tree or network using methods such as split decomposition, neighbor-net, consensus network, super networks methods or methods for computing hybridization or simple recombination networks.
