23/08/14 Taming the BEAST workshop Event1 #714758 Bayesian Evolutionary Analysis by Sampling Trees: Taming the BEAST – August 14 to 18, 2023, Howe Sound Inn & Brewing, Squamish, British Columbia. BEAST 2 is an open source cross-platform software package for analysing genetic sequences in a Bayesian phylogenetic framework. Participants will be equipped with the skills and core knowledge to confidently perform and interpret inference generated from phylogenetic and phylodynamic analyses. |
Summary - BEAST 2 is an open source cross-platform software package for analysing genetic sequences in a Bayesian phylogenetic framework. BEAST 2 provides a growing collection of new models tailored specifically to particular data sets and/or research questions. This marked expansion of methods available in BEAST 2 has resulted in a significant increase in the complexity of the models which can be daunting (i.e. introduce errors or use inappropriate models) for new users. However, this complexity became the wellspring for Taming the BEAST workshops (https://taming-the-beast.org/workshops/) aimed at promoting interaction between BEAST 2 users and developers. Participants have the opportunity to learn from the developers while the developers gather feedback from participants regarding ease of use, platform issues, and user requirements for future software and methods development. Each workshop is an international event that places great emphasis on ensuring a collegial and collaborative atmosphere. The main objective is to provide participants with the skills and core knowledge to confidently perform and interpret inferences generated from phylogenetic and phylodynamic analyses.
- Since its inception, the Taming the BEAST workshop provides a somewhat general overview of BEAST 2, software packages, and applications. The current iteration of the Taming the BEAST workshop incorporated infectious disease transmission modelling to address the current demand for modelling transmission dynamics from molecular sequences (ex: HIV, SARS-CoV-2). BEAST 2 has been cited over 5,000 times and figured predominantly in reconstructing the evolutionary dynamics of viral pandemics of the last four decades including HIV, Influenza A virus subtype H1N1 (A/H1N1), Middle East Respiratory Syndrome Coronavirus (MERS-CoV), Ebola virus, and more recently Severe Acute Respiratory Syndrome Coronavirus-2 (SARS-CoV-2). As such, BEAST 2 is a particularly important tool for building expertise and enhancing capacity for modelling infectious diseases.

Guest lecturers Deliverables Participants will be equipped with the skills and core knowledge to confidently perform and interpret inference generated from phylogenetic and phylodynamic analyses. Furthermore, lectures and tutorials will be publicly available here: https://taming-the-beast.org/workshops/Taming-the-BEAST-SBT/ Schedule Taming the BEAST workshops are one week long (5 days; https://taming-the-beast.org/workshops/Taming-the-BEAST-SBT/). This allows enough time to properly teach the principles of Bayesian evolutionary analysis by sampling trees, explore BEAST software packages, and complete the corresponding hands-on tutorials as well as provide networking opportunities. A unique feature of Taming the BEAST workshops is that there are also planned activities situated in the middle of the week and at least 1-2 group dinners to provide additional opportunities for teachers, participants, and organizers to form meaningful relationships and long-lasting collaborations. The workshop provides an extensive training opportunity for individuals at any stage of their career including post-doctoral, graduate, and undergraduate students.

We introduce and apply Bayesian Reconstruction and Evolutionary Analysis of Transmission Histories (BREATH), a method to simultaneously construct phylogenetic trees and transmission trees using sequence data for a person-to-person outbreak. BREATH’s transmission process that accounts for a flexible natural history of infection (including a latent period if desired) and a separate process for sampling. It allows for unsampled individuals and for individuals to have diverse within-host infections. BREATH also accounts for the fact that an outbreak may still be ongoing at the time of analysis, using a recurrent events approach to account for right truncation. We perform a simulation study to verify our implementation, and apply BREATH to a previously-described 13-year outbreak of tuber-culosis. We find that using a transmission process to inform the phylogenetic reconstruction results in better resolution of the phylogeny (in topology, branch length and tree height) and a more precise estimate of the time of origin of the outbreak. Considerable uncertainty remains about transmission events in the outbreak, but our reconstructed transmission network resolves two major waves of transmission consistent with the previously-described epidemiology, estimates the numbers of unsampled individuals, and describes some highprobability transmission pairs.
An open source implementation of BREATH is available from:
