Mash genomic distance
Websequencing; genomic distance Background Since the release of the seminal Mash tool [1], data sketches such as MinHash have become instrumental in comparative genomics. … Web1 de mar. de 2024 · Distances between the complete plasmid sequences were calculated using Mash (version 2.2) . We then used 1—Mash distances to obtain the similarities.
