k-mer set cluster. Graph of cluster 1 from Table 2. Each node shows the number of k-mers in the set (left number), the number of artificial vectors sharing the k-mer substrings (right number) and the functional annotation. Edges denote common vectors between two nodes. Abbreviations are as follows: DHPS, dihydropteroate synthase; STRA, streptomycin resistance; Kanamycin/Neomycin, Kanamycin/Neomycin resistance; Recombsite, recombination site; Transterm, transcription termination.
