Tracer is a graphical tool for visualization and diagnostics of MCMC output.

Tracer (now at version 1.7) is a software package for visualising and analysing the MCMC trace files generated through Bayesian phylogenetic inference. Tracer provides kernel density estimation, multivariate visualisation, demographic trajectory reconstruction, conditional posterior distribution summary and more. Tracer 1.7 can read output files from MrBayes, BEAST, BEAST2, RevBayes, Migrate, LAMARC and and possibly other MCMC programs from other domains..
