Methods are being developed to characterize epigenomic and epitranscriptomic events beyond base modifications at the single-molecule level, such as nucleosome occupancy and chromatin accessibility72,175,176 and RNA secondary structure184,185. Mapping DNA modifications using ONT sequencing in combination with exogenous methyltransferase treatment (inducing 5mC at GpC sites) led to the development of an experimental and bioinformatics approach, MeSMLR-seq, that maps nucleosome occupancy and chromatin accessibility at the single-molecule level and at long-range scale in S. cerevisiae72 (Table 1). For example, by late 2019, the highest average sequencing length achieved has been 23.8kilobases (kb) using a specific DNA extraction protocol51. 4, middle center). Nanotechnol. Int. Automated library preparation for nanopore sequencing. Processive translocation of a DNA or RNA molecule leads to a characteristic current shift that is determined by multiple consecutive nucleotides (that is, k-mer) defined by the length of the nanopore sensing region1.

Recently, two benchmark studies demonstrated that the existing hybrid error correction tools (for example, FMLRC93, LSC and LorDEC) together with sufficient short-read coverage can reduce the long-read error rate to a level (~14%) similar to that of short reads85,87, whereas self-correction reduces the error rate to ~36% (ref. Nonetheless, current ONT sequencing techniques have several limitations, including relatively high error rates and the requirement for relatively high amounts of nucleic acid material. ONT enables the direct detection of some DNA and RNA modifications by distinguishing their current shifts from those of unmodified bases52,71,72,73,74 (Fig. J. Antimicrob.
