RNA@ (download here) is a RNA annotation tool for prokaryotic organisms based on a lightened
Aho-Corasick like algorithm.
The algorithm encodes a data set of nucleotide sequences into a Finite State Machine able to
recognize every occurrence of every nucleotide sequence into a genome in a single read of the genome.
As nucleotide sequence data set, RNA@ uses a collection of about 300,000 RNA deposited into the NCBI. These
RNA are automatically collected from about 25,000 complete deposited genomes (last update 23-06-2021).
