Males are significantly smaller than females, measuring just 0.6-1.4 in (1.5-3.5 cm) long. The resulting fastq outputs were adapter trimmed, low-quality reads ends trimmed (-q 10), and short reads of <30 base pairs removed using cutadapt version 2.5 (M. Martin, 2011). If you did basecalling with MinKNOW, you can skip this step and go to Demultiplexing.

Note: guppy ships with some pre-configured models that set many basecalling parameters to sensible defaults. The user can choose if he wants to keep and use the precalculated quality values in a chromatogram (computed with his own basecaller) of if DNA Baser will recompute those values. Basecalling with ONT Guppy 5 and 6 super-accurate gave almost identical results, attaining read accuracies of 91.96% and 94.15%.
Pair consensus decoding improves accuracy of neural network basecallers Plant species-specific basecaller improves actual accuracy - figshare Example: In the image below we can see how a 3rd party base caller assigned QV to the bases. 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. We have ran some Coronavirus samples on MinION using MinKnow with the Guppy basecaller on. In the second step, the correct sequence is mapped back to the current measurements.
