Metagenomics is a relatively new field of research based on high-throughput sequencing (or Next Generation Sequencing) and its popularity signifies a growing appreciation for the composition of microbial communities (microbiomes) and the genetic information their genomes carry. Metagenomics allows us to study the microbiome in its natural environment and learn about the cooperative and often symbiotic relationships between prokaryotes, eukaryotes, viruses, and archaea.

In this Omics Logic Metagenomics Specialization, we will explore how different types of analysis can be used to understand the microbial world. We will cover several bioinformatics approaches to the analysis of the microbiome. We will learn to compare microbial composition in different conditions, learn about the sequencing of viral samples and discuss how microbes evade the immune response of the host as well as evade treatment. We will do so in the context of several projects taken from high-impact publications.

Key Topics Covered:

Overview of Methods and Applications for Metagenomics Sequencing and Analysis

A program that embeds data-driven concepts into biological projects, spanning the student learning journey from observer to participant in research. Project-based learning for big data bioinformatics is to go beyond the theory with real datasets, projects, and expert mentors. Work with curated datasets from publicly available repositories with easy-to-follow tutorials.

Big Data Analysis Platform : Metagenomics Analysis on the T-Bioinfo Server

Many types of omics data require step-by-step preparation, exploration, annotation, & visualization to understand. The T-BioInfo platform was designed for big multi-omics data analysis hiding the complexities of data with a user-friendly & intuitive interface that eliminates the need for coding and advanced machine learning algorithms for data integration and mining.

Interpretation and Meaning: Statistical Analysis, Visualization & Interpretation using R

Online bioinformatics coding exercises to learn and explore R and Python scripting and understand how to analyze and visualize -omics data to extract meaningful insights from large biological datasets. Learn, practice, and achieve bioinformatics greatness with concise exercises and interesting challenges right in the comfort of your browser!

Future Directions: Full metagenomic sequencing, metatranscriptomics & functional analysis
Metagenomic sequencing data can be used to analyze microbiome composition & species diversity. In this program, you will learn about processing 16s rRNA data with DADA2, visualizing OTU abundance tables for diversity & using the Phyloseq R package that can help build phylogeny-aware species richness.
