Mash Sketch (version 2.1+galaxy0)

Select a sequence from your history or use one from a tool data table?:

Input sequence:

Sketch name:

Human-readable description of the sketch

Sketch size:

Each sketch will have at most this many non-redundant min-hashes.

K-mer size:

Hashes will be based on strings of this many nucleotides.

Probability threshold for warning about low k-mer size.:

Sketch individual sequences:

e.g. for multi-fastas of single-chromosome genomes or pair-wise gene comparisons.

What it does

Create a sketch file, which is a reduced representation of a sequence or set of sequences (based on min-hashes) that can be used for fast distance estimations. For output, one sketch file will be generated, but it can have multiple sketches within it, divided by sequences or files.
