Taxonomy predictions are written to the
-tabbedout file. The first three fields are (1) query sequence label,
(2) prediction with boostrap values and (3) strand. If the -sintax_cutoff option is
given then predictions are written a second time after applying the confidence threshold, keeping only ranks with high enough
confidence. On V4 reads, using a cutoff of 0.8 gives predictions with similar
accuracy to RDP at 80% bootstrap cutoff.
