To quantify how the principle covariates, climate, continent, and surface material impacted the taxo-213 nomic composition of samples, we performed a Principal Component Analysis (PCA) on our taxonomic 214 data normalized by proportion and identified principal components (PCs) which were strongly associated 215 with a metadata covariate in a positive or negative direction (PCs were centered so an average direction 216 indicates an association). In general, negative controls had 798 lower k-mer complexity, fewer reads, and lower post PCR Qubit scores than case samples and no major Previous studies have reported that microbial species whose relative abundance is negatively cor-803 related with DNA concentration may be contaminants. ./cache/cord-102613-hly07ne3.txt ./txt/cord-102613-hly07ne3.txt
