Hello, the similarity between the species I studied (contig level) and two closely related species (T2T level and 180 contig level) is 90%-95%, using this software to mount chromosomes failed, the details are as follows: ragtag.scaffold.fasta will have some changes, mainly reducing contig a little and increasing gaps a little. However, the result of ragtag.merge.fasta shows no improvement. What parameters need to be modified?
