1 Initial Relative Abundance BarPlot. load data (exported from qiime2 taxa-bar-plots.qzv) Each OTU contributes a proportion of reads that add up to 100% in each sample. The problem with searching for correlations here is that if there is an increase in one OTU, all of the other OTUs must decrease, and this ends up looking like a negative correlation between the increased OTU and everything else when this may not be the case. 1.2.2 What is metadata?. Metadata is a set of data that describes and provides information about other data.
