Private Identify

Identify a genome without uploading it. The sequence is sketched into a sourmash signature in your browser; only the signature leaves your machine.

What happens to your file

Step 1 / Sketch

Signature, not sequence

Your genome is reduced to a compact sourmash signature right here in your browser, using WebAssembly. The sequence itself never leaves your machine. Only the signature is uploaded: a short list of hashes that cannot reconstruct the genome, so unpublished or sensitive assemblies stay entirely yours.

Step 2 / Compare

Ranked against the database

The signature is compared with every genome in genomeRxiv, and the closest relatives are ranked by average nucleotide identity.

Step 3 / Place

A LIN is assigned

Your genome receives its address in the taxonomy: a LIN, the nearest LINgroups and described species, and a phylogenetic tree of its immediate neighborhood.
