Nanopore sequencing, a vital genomic technology, utilises Oxford Nanopore Technologies (ONT) devices to analyse both short and long-native DNA and RNA molecules, holding diverse potential in life sciences. These devices measure ionic current changes as DNA/RNA passes through a nanoscale protein pore, recording 'squiggle' data. Data simulation, crucial for scientists and developers, aids in testing, debugging, and validating new analysis methods without real-world variables. It's used for hypothesis development, experimental design, and benchmarking. The Squigulator was introduced as a tool to generate nanopore current signal data, closely resembling real data from a nanopore device, with 99% similarity to the R9.4.1 chemistry. The upcoming R10.4.1 pore chemistry differs, achieving only 90% similarity. The project's aim is to identify modelling techniques to enhance simulated data for R10.4.1, aligning it more closely with real data.
