Per-base sensitivity and precision of assemblies generated for the 2550 HIV1 genomes dataset. A Assembly sensitivity, defined as the fraction of nucleotides in the reference genomes that are aligned to an assembled contig with a sequence identity at least the value on the x-axis. B Fraction of nucleotides of the reference genomes that are aligned to the longest contigs in the assembly that has a sequence identity of at least the value on the x-axis. C Assembly precision is the fraction of assembled nucleotides contained in alignments to a reference genome with sequence identity at least the value on the x-axis
