Assembly statistics of yeast as a function of the k-mer size and maximal occurrence cut-off used to remove very frequent k-mers from short reads prior to unitig assembly. (a) k-mer profiles for k = 50 bp and k = 75 bp. Cut-offs restrict short reads to different degrees. Note logarithmic axes. (b) Illumina unitigs (left: percentage of remaining short-read data; middle: fraction of the reference genome covered; right: number of unitigs mapping multiple times to reference). (c) Final LazyB assembly left: number of unitigs; middle: fraction of the reference genome covered; right: number of mis-assemblies). x: not enough data to assemble
