Description
Split k-mer analysis (SKA version 2 or SKA2) uses exact matching of split k-mer sequences to align closely related sequences, typically small haploid genomes such as bacteria and viruses. SKA can only align SNPs further than the k-mer length apart, and does not use a gap penalty approach or give alignment scores. However, the advantages are speed and flexibility, particularly the ability to run on a reference-free manner (i.e. including accessory genome variation) on both assemblies and reads.
Note: This is a reimplementation of Simon Harris' SKA package (https://doi.org/10.1101/453142) in the rust language by Johanna von Wachsmann, Simon Harris, and John Lees.
