  • Publication number: 20230223104
    Abstract: Disclosed is a genome reconstruction method using whole genome data. According to the present invention, the genome reconstruction method reduces detection errors by converting a nucleotide sequence having a structural variation into a graph form, and then reconstructing the graph so that the structural variation and the copy number variation have consistent values. Thereafter, the genome arrangement form was restored by constructing a haplotype graph using heterozygous single nucleotide polymorphism information and then finding an Eulerian path with a minimum entropy value.
