Christian Diener will join the Institute for Systems Biology as the Washington Research Foundation Distinguished Postdoctoral Fellow in the Gibbons Lab. Christian is a computational biologist who has worked extensively on yeast systems biology and has recently moved into studying the human microbiome. He completed his PhD in systems biology at the Max Plank Institute for Molecular Genetics and is currently working at the National Institute for Genome Medicine in…
Batch Effects in 16S Datasets Complicate Cross-Study Comparisons High-throughput data generation platforms, like mass-spectrometry, microarrays, and second-generation sequencing are susceptible to batch effects due to run-to-run variation in reagents, equipment, protocols, or personnel. Currently, batch correction methods are not commonly applied to microbiome sequencing datasets. In this paper, we compare different batch-correction methods applied to microbiome case-control studies. We introduce a model-free normalization procedure where features (i.e. bacterial taxa) in…
