Transcription feature plots of predicted ncRNA transcripts. Transcription feature plots of predicted ncRNA transcripts (blue arrows) covering annotated ribosomal RNAs (red arrows). For a detailed legend see figure 2. In the first example the RNAz prediction is shorter than the annotated ncRNA (left), while it is much longer in the second example (right). In both cases the prediction of the transcript boundaries were improved by NOCO RNAc.
