From the perspective of read accuracy, SACall yields better performance in the benchmark than ONT official basecaller Guppy and Albacore. Recent developments since then mostly concern extensions for improved detection of barcodes, faster runtime, . Basecalling and primary data analysis Basecalling can be defined as the process of converting the electrical signals generated by a DNA or RNA strand passing through the nanopore into the corresponding base sequence of the strand. Prerequisites CUDA must be installed, which can be simple or extremely difficult, depending on if the CUDA gods smile on you. In nanopore sequencing, sequencing accuracy depends on the library preparation kit version used, the Guppy_basecaller version used, and its basecalling model. Review Reports Citation Export BibTeX . The basecaller translates the raw electrical signal from the sequencer into a nucleotide sequence in fastq format. The main limitation of current diagnostic testing is the inability to combine broad and sensitive pathogen detection with the identification of key strains, pathovars, and subspecies. You can lump all of these results into a single fastq file at the end of basecalling using the final `cat` command, which uses a wildcard to write all of the files with the `*.fastq` extension to a single fastq file.
