New paper up on bioRxiv! This is my third and hopefully final paper on rarefaction. It's still better than the other available methods.

www.biorxiv.org/content/10.6...
Rarefaction is better than robust Aitchison PCA and other compositional data analysis methods at controlling for uneven sequencing effort
Amplicon sequencing typically results in a wide distribution in the number of sequences obtained from each sample. How best to account for this variation has been a persistent problem in the microbial...

A 5-year long experiment, super impressive! I wonder whether the offspring of the final generation would have retained the performance difference, esp. after controlling for seed size/maternal investment.
