In Statistical Analysis of Microbiome Data with R, 1–27. Bioinformatic analysis of microbiome data. Xia, Yinglin, Jun Sun, and Ding-Geng Chen. Applied and Environmental Microbiology 75 (23): 7537–7541. Introducing mothur: open-source, platform-independent, community-supported software for describing and comparing microbial communities. A review of software for analyzing molecular sequences. Search and clustering orders of magnitude faster than BLAST. PyNAST: A flexible tool for aligning sequences to a template alignment. QIIME allows analysis of high-throughput community sequencing data. qiime feature-table rarefy command was used to rarefy all samples into same. DADA2: High-resolution sample inference from Illumina amplicon data. By using qiime dada2 denoise-paired command, reads were denoised into. Reproducible, interactive, scalable and extensible microbiome data science using QIIME 2.

Deblur rapidly resolves single-nucleotide community sequence patterns. Navas-Molina, Evguenia Kopylova, James T. See Waste Not, Want Not: Why Rarefying Microbiome Data Is Inadmissible for some helpful further details on why you shouldn't be doing the subsampling.Amir, Amnon, Daniel McDonald, Jose A. This effect is much attenuated in DADA2 output for a lot of datasets I've looked at, and in these cases, rarefying would then just be a noisy, badly-principled version of relative abundance with a dollop of minimum value filtering. DADA2 actually does a pretty good job addressing one of the major artifacts that motivates people to rarefy in the first place - spurious OTUs resulting in richness that is strongly correlated to sequence depth. Don't do that, especially not upstream of the documented part of your analysis workflow. The phyloseq package already provides many means for transforming your data as-needed. Any transformation, normalization should be done in a way that it is easy to substitute and reproduce. This would be structuring your analysis workflow to throw away information.
