MinION sequencers from Oxford Nanopore are pocket size USB-connected devices that can be used in many applications from virus genomic surveillance to on-site sequencing at the International Space Station. As DNA passes through nanopores embedded in the device, it produces a raw electrical signal which is then translated to a sequence through computational process called base calling, typically employing deep neural networks. In many computational pipelines, base calling is a bottleneck, both from the point of view of accuracy and computational time.
I will first talk about methods that we have developed to make base calling more efficient. In the second part, we will introduce some problems where base calling can be skipped altogether by analyzing the raw sequencing signals directly.
