For ONT sequencing, we extracted genomic DNA from muscle using the phenol-chloroform-isoamyl alcohol extraction, followed by isopropanol precipitation. The DNA was further purified with NucleoBond AXG 100 columns with the NucleoBond Buffer Set IV (Macherey-Nagel, Germany). ONT libraries were prepared with the Ligation Sequencing Kit (SQK-LSK109; Oxford Nanopore Technologies, UK) and were sequenced using multiple R9.4.1 flow cells on an ONT GridION platform. The raw .fast5 files were base-called by Guppy v4.0.11 with the high-accuracy mode and quality filtering. Reads that were shorter than 1 kb were discarded using SeqKit v0.12.0 (Shen et al. 2016 (link)). The length-filtered ONT long reads were used in the downstream analyses. Supplementary Table S3 summarizes the filtered genomic reads generated in this study.
