  1. README. License. Mash is normally distributed as a dependency-free binary for Linux or OSX (see https://github.com/marbl/Mash/releases ). This source distribution is intended for other operating systems or for development. Mash requires c++14 to build, which is available in and GCC >= 5 and XCode >= 6.

  2. 20 de jun. de 2016 · Mash is a software tool that uses MinHash sketches to rapidly compare large sequences and sequence sets. It can be used for clustering, searching, and measuring mutation distance between genomes and metagenomes.

  3. Since MinHash distances are probabilistic estimates, it is important to consider the probability of seeing a given distance by chance. mash dist thus provides p-values with distance estimations. Lower p-values correspond to more confident distance estimations, and will often be rounded down to 0 due to floating point limits.

  4. Screening a read set for containment of RefSeq genomes ¶. (new in Mash v2.0) If a read set potentially has multiple genomes, it can be “screened” against the database to estimate how well each genome is contained in the read set. We can use the SRA Toolkit to download ERR024951: fastq-dump ERR024951. …and screen it against Refseq Genomes ...
