Mash

Introduction

MinHash is a general dimensionality-reduction technique and it is used by Mash to reduce large sequences and sequence sets to small, representative sketches with the result that global mutation distances (Mash distances) can be rapidly estimated.

Other aspects

• terms itself as an alignment-free method

Usage

Typical analysis

Mash is run on genomes. These will usually be de-novo assembled genomes from tools such as Velvet or SPAdes.
