In addition to official ONT tools (for example, ont_fast5_api software for format conversion between single-fast5 and multi-fast5 and data compression/decompression), several third-party software packages40,58,59,60,61,62 have been developed for quality control, format conversion (for example, NanoR63 for generating fastq files from fast5 files containing sequence information), data exploration and visualization of the raw ONT data (for example, Poretools64, NanoPack65 and PyPore66) and for after base-calling data analyses (for example, AlignQC42 and BulkVis49) (Fig. Nat. 30, 344348 (2012). The DNA extraction and purification methods used in these independent studies are summarized in Supplementary Table 1. Oxford nanopore is high throughput, meaning you can sequence a whole genome in a relatively short period of time without the need to break up the genome into many smaller sequences that methods such as illumina's need.
