Goals for these slides: only pointers

• Phyloseq: Data integration
• Transformations, filtering
• Testing tools: networks, hierarchical testing, DESeq2, ..
• Data integration, CCA, DPCOA,..
• Reproducible Research: available Rmd files

Phyloseq

Phyloseq API

Heterogeneous Data Objects: S4 classes

(McMurdie and Holmes, 2013, Plos ONE).

phyloseq-measures-ggplot2

Variance stabilizing using DESeq2

Wolfgang Huber

The way the authors proceed is to follow the rarefying path, this is not recommended and a much better procedure is to use DESeq with phyloseq, see the wiki here:

DESeq with phyloseq wiki

phyloseq-testing-deseq

Waste Not want not supplement

Testing links between communities and factor covariates

phyloseq-networks

Friedman Rafsky Tests

Package: phyloseqGraphTest

Hierarchical testing (Kris Sankaran)

Using the tree

In the Workflow

Taking account of the phylogenetic tree when testing:

• CRAN package: structSSI
  
• Journ. Stat. Software paper JSS link

Multiple table analyses

Sparse Canonical Correlation Analysis:

Triplot

In the Workflow

Modulated DPCoA

DPCoA start with taxa

CRAN package (with shiny adaptation): adaptiveGPCA

Multiple choices: example of the Enterotypes data:

Reproducible Research

Longitudinal Data Analyses

Perturbation Design

Vaginal Microbiome and Pregnancy

Markov Model

All Rmd and htmls for PNAS
