Phylogenetic Tree Samples from BEAST2 Bayesian Analysis

Two Bayesian phylogenetic analyses performed with BEAST2 software, containing 100,000 sampled trees per run along with log files and configuration XML. The dataset was created by author Jonathan Klawitter and published on figshare in March 2026. It supports research related to a paper referenced on arXiv.

Use Cases

• Assess MCMC convergence by analyzing trace statistics in the log files.
• Compare posterior tree distributions between the two runs using the 100,000 sampled trees.
• Reproduce or validate the BEAST2 analysis setup using the provided base XML configuration file.
• Study topological uncertainty by summarizing clade support across the tree samples.

Strengths

• Contains 100,000 phylogenetic trees per analysis run, providing a dense sample of the posterior distribution.
• Includes complete analysis artifacts: tree files, log files, and the base XML, enabling full reproducibility.

Limitations

• The dataset size of 1.7 GB is substantial for a set of two runs, which may limit accessibility.
• Lacks metadata describing the specific biological dataset (DS1-11) used as input for the analyses.
• No information on the number of taxa or sequence length, making prior assessment of model complexity difficult.
