Error rates on synthetic data. The ratio of the number of aligned nucleotide pairs that are incorrect compared to the reference alignments, as a fraction of the total number of aligned nucleotide pairs in the reference alignments; plotted as a function function of the conservation rate q between the sequences and their common ancestor. Notably, this is more than 1 for some programs at low q: this means the number of incorrect alignments that they make exceeds the number of correct alignments in the reference alignment.
