Tree log – log every
Number of the MCMC steps before a tree sample is being logged.
Usually, a total of ten thousand samples in the tree log is sufficient, and having more samples only wastes disk space and makes processing the tree log more cumbersome. So, taking the total number of MCMC steps and divide this by 10.000 makes a good value for
Note that the required chain length differs between data sets and models, so that is a value that needs to be established by a bit of experimentation.
It is probably a good idea to keep the
logEvery of the tree log the same as that of the trace log.
