Transcription feature plots of ncRNA transcripts. Transcription feature plots of ncRNA transcripts predicted by NOCO RNAc (blue arrows) covering annotated ribosomal RNAs (red arrows). The SIDD profile of the genomic region is drawn as a black graph (related scale on the y-axis). The coordinates of the genomic region are denoted on the x-axis. The ncRNA locus predicted by RNAz is shown as a black line. Predicted Rho-independent terminator signals are depicted as short black arrows. NOCO RNAc considers the properties of the predicted transcription features (free energy value of SIDD sites; confidence value for terminators) and not only their position to predict the strand.
