Accuracy versus distance to sister taxon: COG simulation. The relationship between accuracy and phylogenetic (sum of branch length) distance to the sister taxon for the COG simulation. For each taxon in each alignment, the phylogenetic distance to the closest sister taxon was calculated, along with the average placement error for the ten reads simulated from that taxon in that alignment. The results were binned and shown in boxplot form, with the central line showing the median, the box showing the interquartile range, and the "whiskers" showing the extent of values which are with 1.5 times the interquartile range beyond the lower and upper quartiles. Outliers eliminated for clarity.
