Comparison of pipeline relative abundance assessment feature-level error metrics. Distribution of feature-level relative abundance (a) bias metric is the median error rate and (b) variance is the robust coefficient of variation (RCOV=IQR/|median error rate|) by individual and pipeline. For both the bias and variance metrics, lower values are better. Boxplot outliers, 1.5×IQR from the median were excluded from the figure to prevent extreme metric values from obscuring metric value visual comparisons
