For users needing very long runs of MrBayes, | For users needing very long runs of MrBayes, we suggest you break up the work into several small jobs rather than one very long job. Long jobs have are more likely to be interrupted a hardware failure or a maintenance outage. Fortunately, MrBayes has a built-in mechanism for creating checkpoints, where progress can be saved from one job and continued in a subsequent job. | ||
