 For diploid haplotype-resolved genome assembly, hifiasm can further enhance assembly contiguity 
 by introducing scaffolding. It leverages the assemblies of the two haplotypes to scaffold each other. 
 Specifically, if there is a gap within the haplotype 1 assembly, hifiasm will use the corresponding 
-homologous region in haplotype 2 to scaffold haplotype 1. Below is an example using the `--dual-scaf` option:
