Inference and Analysis of SPIEC-EASI Microbiome Networks

Methods Mol Biol. 2021:2232:155-171. doi: 10.1007/978-1-0716-1040-4_14.

Abstract

Network analysis facilitates examination of the interactions between different populations in a community. It can provide a range of metrics describing the social characteristics of each population and emergent structural properties of the community, which may be used to address novel ecological questions. Using a publicly available dataset, this chapter provides point-by-point code and instructions to infer and analyze a SPIEC-EASI (SParse InversE Covariance Estimation for Ecological Association Inference) network using free, open source software (R and Gephi).

Keywords: Amplicon; Covariance; Interactions; Microbiome; Networks; SPIEC-EASI.
