Reproducible, interactive, scalable and extensible microbiome data science using QIIME 2

Stability of operational taxonomic units: an important but neglected property for analyzing microbial diversity

As a compromise to the factors listed above, we propose using an open-reference method to enhance OTU stability. This type of method clusters sequences against a database and in...

Linking Long-Term Dietary Patterns with Gut Microbial Enterotypes

The basic composition of the human gut microbiome is influenced by long-term diet: high fat and protein versus high fiber.

Ultra-high-throughput microbial community analysis on the Illumina HiSeq and MiSeq platforms

Abstract DNA sequencing continues to decrease in cost with the Illumina HiSeq2000 generating up to 600 Gb of paired-end 100 base reads in a ten-day run. Here we present a protoc...
