From: The effect of DNA extraction methodology on gut microbiota research applications
The effect of the DNA extraction methods on the compositional similarity using different β-diversity measures. a considers using Bray-Curtis distance based on OTU abundances alone, and b unweighted Unifrac distance. c, d are then the resulting beta diversity estimates using the BAT package. The lightest shade/smallest value in a given row/column represents the most similar sample in terms of community profile. ED, AB, IM correspond to the three faecal sample and VSL to the proprietary probiotic capsule ID respectively. Technical replicates represented by 1 and 2 in the sample names
