Ratio of corrected N50 versus raw contig sizes for all assemblies of R. sphaeroides . Corrected N50 sizes were computed using the GAGE metrics . The dashed vertical line indicates the auto-selected k of 35 chosen by KmerGenie. The individual points indicate assemblies from GAGE-B. For 3 of 11 assemblers, the automated k-mer selection provides the best corrected N50. Additionally, for 9 of the 11 assemblers, the automated k-mer selection provides a corrected to raw N50 ratio within 10% of the optimal.
