Identification of potential sRNA. (a) Criterion for identifying potential sRNA. If a promoter located upstream of the expressed intergenic region (EIR) or a rho-independent terminator located downstream of the EIR, either in the forward or the reverse strands of the genome is identified, then the EIR is classified as a potential sRNA. (b) & (c) a promoter was identified upstream of the EIR in both the cases and the EIRs were classified as sRNA.
