  1. All statistics are from the haploid and diploid human genome NA12878 assembly. KAT comp was run once and three times to generate the equivalent spectra-cn plots generated with Merqury. In addition to the spectra-cn plots, Merqury simultaneously generates spectra-asm, QV and k-mer completeness statistics, which are not available in KAT. Runtimes were measured on Intel(R) Xeon(R) Gold 6140 CPU, with 2.30 GHz, using a maximum of 24 cores. CPU time is measuring runtime assuming a single core for comparison. Maximum memory footprint is reported in Max mem
