Tracer_1.5

Tracer 1.5 is a cross‑platform, Java‑based application from the BEAST development team that helps you explore, diagnose, and summarize Markov chain Monte Carlo (MCMC) output. It loads one or more log files from BEAST and other compatible Bayesian phylogenetic programs, visualizes traces and posterior distributions, and reports the statistics you need to assess convergence and mixing with confidence.

Key features:

• Reads BEAST .log files and other tab‑delimited trace files with headers
• Interactive trace plots to assess stationarity and mixing
• Posterior density plots and histograms for parameter distributions
• Summary statistics, including mean, median, standard deviation, 95% HPD intervals, and effective sample sizes (ESS)
• Flexible burn‑in handling with instant recomputation of summaries
• Side‑by‑side comparison of multiple runs to check consistency
• Parameter filtering, sorting, and quick selection of subsets
• Export of summaries and figures for reporting and reproducibility

Typical uses:

• Verifying MCMC convergence and diagnosing poor mixing
• Choosing appropriate burn‑in and sampling intervals
• Reporting posterior estimates with credible intervals
• Comparing independent runs for robustness

Compatibility:

• Works on Windows, macOS, and Linux
• Java-based; requires a compatible Java Runtime Environment
• Optimized for BEAST outputs but can read generic tab‑delimited logs with column headers

Getting started:
Open your .log files, set an appropriate burn‑in, review ESS values (commonly aiming for 200 or higher), and inspect trace and density plots. Use the summary panel to copy or export statistics for your analysis or publication.
