Precision-recall (PR) curves for HmmUFOtu taxonomic assignment results on four simulated datasets: (a) random; (b) V4; (c) V1 V3; (d) V3 V5. True positive (TP) and true negative (TN) are defined as both the known and assigned taxonomy having or not having a certain level of taxonomy annotation, respectively. PR curves are calculated by varying the assignment Q-score threshold from 0 to 10 with a step of 1, then 20, 30, 40, 50, 60, and 250 (the maximum value)
