how to assign annotated gene structure (from contigs) to chromosome coordinate(from HiC)?

Question

[ward200w]

Dear All: I'm a beginner of genome biology. I have assembly(de novo) a animal gemome which consists of contigs using nanopore sequencing tech. and I already annotated the gene structure(GFF file and fasta of contigs).Then ,in order to get a better assembly for chromosome-level research.I got a Hi-C squencing process.now I have the chromosome fasta file.But I don't know how to assign gene structure(gene\CDS\mRNA) to the Hi-C results.could you give me some advice or some software helpful?Thanks ！
