Pipeline components for real-time virus analysis


The nextstrain project is an attempt to make flexible informatic pipelines and visualization tools to track ongoing pathogen evolution as sequence data emerges. The nextstrain project derives from nextflu, which was specific to influenza evolution.

nextstrain is comprised of three components:

  • fauna: database and IO scripts for sequence and serological data
  • augur: informatic pipelines to conduct inferences from raw data
  • auspice: web app to visualize resulting inferences


Definition: One held to foretell events by omens.

Augur is the informatic processing pipeline to track evolution from sequence and serological data. It is broken into two parts, termed prepare and process, which result in output JSONs for Auspice (click for documentation).
