To date, Guppy is the most widely used base caller because of its superiority in accuracy and speed32 (Table 1). Nanopore sensing is a direct electronic analysis of the target molecule, Sequencing native DNA (and RNA) avoids bias introduced by amplification steps, opening up opportunities for epigenetic analysis, Workflows are kept simple by avoiding amplification or light-based measurement steps. BMC Bioinformatics 18, 204 (2017). These approaches take into account not only general assembly performance but also certain specific aspects, such as complex genomic regions and computational intensity. Roach, N. P. et al. These breakthroughs have required extensive development of experimental and bioinformatics methods to fully exploit nanopore long reads for investigations of genomes, transcriptomes, epigenomes and epitranscriptomes. The portability of the MinION system, which consists of the palm-sized MinION, mobile DNA extraction devices (for example, VolTRAX and Bento Lab) and real-time onboard base calling with Guppy and other offline bioinformatics tools, enables field research in scenarios where samples are hard to culture or store or where rapid genomic information is needed233.
