A total of 62,904 reads were generated through sequencing, with an N50 length of 9,919 bp. Adapter sequences from the Nanopore library were removed using Porechop (v0.2.4). Subsequent filtering with NanoFilt (v2.8.0) and further adapter trimming resulted in a refined dataset of 58,611 reads. These long reads were then assembled de novo using Flye assembler (v2.9.3-b1797), producing two contigs. The assembly was polished through four rounds of Racon (v1.5.0), followed by a final polishing step with Medaka (v2.0.1).
