PromethION, a high-throughput device for large-scale projects, has 24 or 48 parallel flow cells (up to 3,000 channels per flow cell). In particular, several transcript assemblers have been developed specifically for error-prone long reads, such as Traphlor124, FLAIR123, StringTie2 (ref. Manrao, E. A. et al. Nanopore sequencing is being applied in genome assembly, full-length transcript detection and base modification detection and in more specialized areas, such as rapid clinical diagnoses and outbreak surveillance. In 2018, distinct ionic current signals for unmodified and modified bases (for example, m6A and m5C) in ONT direct RNA-sequencing data were reported52. Although the ultralong read length of ONT data remains its principal strength, further increases in read length would be beneficial, further facilitating genome assembly and the sequencing of difficult to analyze genomic regions (for example, eukaryotic centromeres and telomeres).

For instance, ONT data alone were used to assemble the first genome of Rhizoctonia solani (a pathogenic fungal species that causes damping-off diseases in a wide range of crops)142, and hybrid sequencing data (ONT plus Illumina) were used to assemble the first draft genomes of Maccullochella peelii (Australias largest freshwater fish)143 and Amphiprion ocellaris (the common clown fish)144. van Dijk, E.

However, this review focuses on ONT technology as it has been used in most peer-reviewed studies of nanopore sequencing, data, analyses and applications. In May 2017, ONT released the 1D2 method together with the R9.5 nanopore; in this method, instead of being physically connected by a hairpin adapter, each strand is ligated separately to a special adapter (Fig. Nat. & Loman, N.

Subsequently, a mutant CsgG and a new motor enzyme (whose origin was not disclosed) were integrated into R9.4 to achieve higher sequencing accuracy (~8594% as reported in refs. Rautiainen, M. & Marschall, T. GraphAligner: rapid and versatile sequence-to-graph alignment. 43, e116 (2015). Nanopore sequencing is rapidly becoming one of the fastest and least expensive methods for deciphering genetic variations at the molecular level. Compared to PacBio, ONT performs better in detecting 5mC but has lower accuracy in detecting 6mA68,75,81. The size of a staplerand USB-powered, the MinION is beingused outside the traditional lab environment, enabling users to takeanalysis to the sample. For example, Flye improves genome assembly at long and highly repetitive regions by constructing an assembly graph from concatenated disjoint genomic segments110; Miniasm uses all-versus-all read self-mapping for ultrafast assembly107, although postassembly polishing is necessary for higher accuracy. Therefore, new advanced sequencing techniques were developed with time to overcome these problems. Chem. Commun. Comput.

The DNA extraction and purification methods used in these independent studies are summarized in Supplementary Table 1. They would require specific experimental protocols (for example, identifying chromatin accessibility by detecting artificial 5mC footprints72,175,176) rather than the simple generation of long reads. In both cases, only the RNA strand passes through the nanopore, and therefore direct sequencing of RNA molecules does not generate a consensus sequence (for example, 2D or 1D2).
