design: High-molecular-weight DNA was extracted using a modified CTAB-based method (https://dx.doi.org/10.17504/protocols.io.b5qyq5xw) with precipitation in 40% isopropanol on glass beads. The genomic library for long reads was prepared using the Native Barcoding kit (SQK-NBD114, ONT) with semi-selective DNA precipitation for long fragment enrichment (https://nanoporetech.com/document/extraction-method/size-selection2) and sequenced on four MinION flowcells (FLO-MIN114, ONT). Raw signal was basecalled with Dorado v0.7.3 in the duplex mode using the SUP model v4.1.0 for 260 bps signal and v.5.0.0 for 400 bps. Subsequently, the reads were trimmed with Dorado and filtered by a quality score of 7 using Chopper v0.5.0.
