Logan Search: A k-mer search for all Sequence Read public accessions

Logan Search is a k-mer search engine for all Sequence Read Archive public accessions (as of dec 2023). Given a DNA sequence, the service replies in a few minutes in which SRA accession(s) it is likely to occur. The service also enables to recover metadata associated to target accessions, and to perform some visualizations.

In more technical depth, the search engine uses kmindex. It was applied to construct an index over all genome assemblies of all of SRA, more specifically over the unitigs of Logan. The website relies on kmviz.
