Before revision:  We then apply our algorithm to the problem of obtaining distances between whole-genome sequencing samples , a key part of modern metagenomics analysis and an evergrowing need due to the increasing availability of high-throughput DNA sequencing data.
After revision:  We then apply our algorithm to obtain similarity among all pairs of a set of large samples of genomes. This task is a key part of modern metagenomics analysis and an evergrowing need due to the increasing availability of high-throughput DNA sequencing data.
