Figure 3From: All-Food-Seq (AFS): a quantifiable screen for species in biological samples by deep DNA sequencingDetermination of the optimal number of sequence reads necessary to obtain accurate quantification results for species components. The number of sequence reads used in the mapping (x-axis) was plotted against the values of mapping accuracy (y-axis), calculated as the cumulated absolute deviation in% of mapping results versus expected species proportions.Back to article page
