[…] estimates are given in table 4 within ., our results suggest that once the patient samples are taken, the patients are unlikely to continue transmitting to others. in fact, the median number of sampled ancestors for most rmds clusters is zero. very few clusters belonging to the 215d, 108i, 181c and 190a data sets have significantly more than zero sampled ancestors. overall, the probability […]

[…] assessment of clocklike behavior (for further description of all methods, as well as all data and scripts used, see )., tip-dating in beast2 (; ) with birth-death-serial sampling (bdss) or sa-bdss (sampled ancestors) tree models (; ) requires a specialized xml input file. to set this up, we used beastmaster (; ; ), a set of r functions that convert nexus character matrices, an excel file […]

[…] at the boundary between micro- and macroevolution (). the recognition of ancestor-descendant relationships in fossils is debated (; ; ; ). in this study, 95% of the sampled trees include a number of sampled ancestors ranging between 0 and 14 (median value, 7; ). this value suggests that up to 23% of the specimens collected in the sample may represent members of populations that are anagenetic […]

[…] until recently, combining the fbd model with a total-evidence dating approach was complicated by the fact that existing implementations of the mcmc algorithm over tree space did not allow trees with sampled ancestors. addressed this problem and enabled full bayesian inference using fbd model in the beast2 software () with the sa package ( […]
