Non-coding RNAs (ncRNAs) are transcripts that do not code for proteins. Recent find-
ings have shown that RNA-mediated regulatory mechanisms influence a substantial por-
tion of typical microbial genomes. We present an efficient method for finding potential
ncRNAs in bacteria by clustering genomic sequences based on homology inferred from
both primary sequence and secondary structure. We evaluate our approach using a set
of Firmicutes sequences, and the results show promise for discovering new ncRNAs.
