IDP-denovo: de novo transcriptome assembly and isoform annotation by hybrid sequencing. The principal concern in many applications is the error rate, which, at 615% for the R9.4 nanopore, is still much higher than that of Illumina short-read sequencing (0.11%). Because ONT devices do not require high-end computing resources or advanced skills for basic data processing, many laboratories can run data collection themselves. Oikonomopoulos, S., Wang, Y.

Bolognini, D., Magi, A., Benes, V., Korbel, J. O. BackgroundEmerging long reads sequencing technology has greatly changed the landscape of whole-genome sequencing, enabling scientists to contribute to decoding the genetic information of non-model species. Nanopore sequencing is the only sequencing technology that offers real-time analysis (for rapid insights), in fully scalable formats, can analyse native DNA or RNA, and sequence any length of fragment to achieve short to ultra-long read lengths. 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. However, detection of RNA modifications with single-nucleotide resolution at the single-molecule level has yet to be demonstrated. PLoS Comput. Commun. Genet.
