*Local errors include inversions and transpositions within a contig or that cause the order of contigs to be incorrect within a scaffold. ^†Interleaving failures are cases where it has not been recognized that two scaffolds overlap because the end contig in one scaffold lies in a gap in the adjacent scaffold. ^‡Repeat errors are incorrect assemblies of transposable elements (see text for description). ^§Gross misassemblies are cases in which scaffolds themselves are out of order.
