LongQC: a quality control tool for third generation sequencing long read data. MinION nanopore sequencing identifies the position and structure of a bacterial antibiotic resistance island. BMC Bioinformatics 21, 136 (2020). 28, 266274 (2018). To meet the needs of different project scales, ONT released several platforms (Box 1). Biol. Gigascience 8, giz043 (2019). 5). More recently, Pacbio and Oxford Nanopore long read sequencing are also being used for assemblies as these reads are 10kb or longer on average. Deamer, D., Akeson, M. & Branton, D. Three decades of nanopore sequencing. Nanopore sequencing measures changes in ionic current when single-stranded DNA fragments are moved through a nanopore, which are very small proteins forming pores are embedded within a membrane .
