WebK-mer Based Tree Construction () Is a distance-based method that can create trees based on multiple single sequences. K-mers are used to compute distance matrices for distance-based phylogenetic reconstruction tools such as neighbor joining and UPGMA (see Distance-based methods ). This method is less precise than the "Create Tree" tool but it ...
