  <help>
Neptune locates genomic signatures using an exact k-mer matching strategy while
accommodating k-mer mismatches. The software identifies sequences that are
sufficiently represented within inclusion targets and sufficiently absent from
exclusion targets. The signature discovery process is accomplished using
probabilistic models instead of heuristic strategies.

The inclusion and exclusion targets must be FASTA files.
