Course Overview

This course was designed to teach the basics of targeted amplicon data processing and analysis using the QIIME2 platform. Attendees will learn how to format data and metadata, import data, demultiplex sequences, trim sequences, denoise and classify sequences, and conduct basic analyses including measures of alpha and betadiversity.

Content from this course was inspired by the QIIME 2 Cancer Microbiome Intervention Tutorial provided by the QIIME2 developers. While much of the code used from that tutorial will be integrated into these lessons, this course does not seek to replicate tutorial materials already available on the QIIME2 website (See the QIIME2 youtube playlist for detailed lessons).

This course will include seven 1 - 1.25 hour lectures followed by a 45 minute optional practice session. Lessons will be on Mondays and Wednesdays from 1 - 2:15 pm.

Lesson topics:

Lesson 1: Toward fully reproducible microbiome multi-omics bioinformatics with QIIME 2 (Oct 19th)

Lesson 1 will not include a hands on component, but rather will include an introduction to QIIME2 by guest speaker, Greg Caporaso, a leading developer of the QIIME2 platform.

Who can take this course?

There are no prerequisites to take this course. However, learners should have basic unix skills (e.g., know how to navigate directories, copy, move, and download files from the web). This course is open to NCI researchers interested in using the QIIME2 platform to process and analyze microbiome data.

What materials are needed to take this course?

To participate in this course, you will need a computer, a reliable internet connection, and a web browser. All classes and help sessions will be held virtually through Webex. This class will be taught using the GOLD learning environment on the DNAnexus platform. Learners will need to sign up for a DNAnexus account and send their user name to
