Overview

Genomic Epidemiology is an important approach in the effort to mitigate disease transmission. An often-critical step is generating phylogenetic trees to explore the genetic relationship between viruses on a local, national or global scale. The Augur workflows facilitate this for viral pathogens by generating files for the visualization of phylogenetic trees with accompanying metadata.

Two workflows are offered: Augur_Prep_PHB and Augur_PHB. These must be run sequentially to first prepare each individual sample for running Augur, and second to run Augur itself on the set of samples, generating the phylogenetic tree files with accompanying metadata. The outputs from these workflows can be visualized in Auspice and UShER.
