Hierarchical clustering of CAMI short read microbiome samples [32]. Heatmaps show the pairwise Jaccard similarity between microbiome samples (ranging from 0% (blue) to 100% (red)); colormap ranges are computed using robust quantiles and dendrogram clades are coloured by body site. a HULK histosketches (k-mer size = 21, histosketch size = 512) for 48 microbiome samples were sketched in 1 min 30 s (12 cores per histosketch). b sourmash MinHash sketches (k-mer size = 21, sketch size = 512, track abundance = true) for 48 samples were sketched in 25 min 17 s. c Simka k-mer spectra (k-mer size = 21) for 48 microbiome samples were computed in 24 min 1 s (12 cores per spectrum)
