Microbiome Network Ecology & Co Occurrence — Hands-on

Learn how to build and interpret microbiome co occurrence and interaction style networks from amplicon and metagenomic data. This module walks through correlation and graphical models, community detection, keystone taxa and stability concepts so you can convert microbiome tables into ecological network insights for clinical, environmental and industrial studies.

Microbiome Network Ecology Foundations

Networks in microbiome and microbial ecology studies

nodes as taxa, functions and samples edges as associations and candidate interactions use cases in health, environment and industry

Types of microbiome association networks

correlation and covariance networks graphical models and sparse inverse covariance time ordered and bipartite style networks

Compositionality, sparsity and confounding in networks

why naive correlations can mislead sparsity, zero inflation and prevalence filters batch effects and shared environment issues

Session 2

Fee: Rs 11800

Co Occurrence Network Construction Workflows

Preparing feature tables for network analysis

choosing taxonomic or functional resolution prevalence and abundance filtering rules normalisation and transform options

Correlation and composition aware association methods

Spearman and Pearson baselines SparCC style and related methods graphical lasso or SPIEC style approaches

Thresholding, multiple testing and edge confidence

p values, FDR and effect size trade offs symmetric vs directed edge choices exporting networks for downstream tools
