For example, the integration and automation of DNA/RNA extraction systems, sequencing library preparation and loading systems would allow users without specific training to generate ONT sequencing data. Although the average accuracy of ONT sequencing is improving, certain subsets of reads or read fragments have very low accuracy, and the error rates of both 1D reads and 2D/1D2 reads are still much higher than those of short reads generated by next-generation sequencing technologies. In addition, ONT direct RNA sequencing has been used to construct RNA viral genomes while eliminating the need for the conventional reverse transcription step, including Mayaro virus150, Venezuelan equine encephalitis virus150, chikungunya virus150, Zika virus150, vesicular stomatitis Indiana virus150, Oropouche virus150, influenza A53 and human coronavirus86.
