Phylogenetic Tree Summarization and Annotation

SumTrees is a program to summarize non-parameteric bootstrap or Bayesian posterior probability support for splits or clades on phylogenetic trees.

The basis of the support assessment is typically given by a set of non-parametric bootstrap replicate tree samples produced by programs such as GARLI or RAxML, or by a set of MCMC tree samples produced by programs such as Mr. Bayes or BEAST. The proportion of trees out of the samples in which a particular split is found is taken to be the degree of support for that split as indicated by the samples. The samples that are the basis of the support can be distributed across multiple files, and a burn-in option allows for an initial number of trees in each file to be excluded from the analysis if they are not considered to be drawn from the true support distribution.
