About Nextstrain

Nextstrain is an open-source project to harness the scientific and public health potential of pathogen genome data. We provide a continually-updated view of publicly available data with powerful analytics and visualizations showing pathogen evolution and epidemic spread. Our goal is to aid epidemiological understanding and improve outbreak response.

Resulting data and inferences are available live at the website nextstrain.org.

About Augur

Definition: One held to foretell events by omens.

Augur is the bioinformatics toolkit we use to track evolution from sequence and serological data. It provides a collection of commands which are designed to be composable into larger processing pipelines.

The output of augur is a series of JSONs that can be used to visualize your results using Auspice.

Quickstart

Follow instructions to install Augur. Try out an analysis of real virus data by completing the Zika tutorial.
