The architecture of SARS-CoV-2 transcriptome. 100), and a new mode of STAR, which was originally developed for short reads101, have been widely used in splice-aware alignment of error-prone transcriptome long reads to genomes. 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). R9.5 was introduced to be compatible with the 1D2 sequencing strategy, which measures a single DNA molecule twice (see below). The analysis of proteins and peptides with nanopores, however, is complicated by the complex physicochemical structure of polypeptides and the lack of understanding of the mechanism of capture and recognition of polypeptides by nanopores.
