Hapo-G

Hapo-G applies haplotype-aware polishing to genome assemblies, improving base accuracy in diploid and heterozygous genomes by using phasing information and integrating short-read and long-read sequencing data from technologies such as Pacific Biosciences and Oxford Nanopore.

Key Features:

• Haplotype-Aware Polishing: Incorporates phasing information to distinguish and preserve the two haplotypes in diploid genomes, reducing haplotype switching and protecting coding-region integrity.
• Integration of High-Quality Reads: Combines short-read (high-accuracy) and long-read (long-contiguity) sequencing data, supporting platforms such as Pacific Biosciences and Oxford Nanopore to leverage their complementary strengths.
• Enhanced Assembly Quality: Produces consensus sequences that accurately reflect both alleles in diploid organisms, improving base-level accuracy and reducing errors like premature stop codons in coding regions.

Scientific Applications:

• Diploid and heterozygous genome assembly polishing: Polishing assemblies to generate haplotype-consistent consensus sequences for diploid and heterozygous genomes.
• Gene function and coding-sequence analysis: Improving base accuracy in coding regions to avoid artifacts that affect gene annotation and functional interpretation.
• Evolutionary biology and personalized medicine: Enabling more reliable downstream analyses that require accurate individual genotypes for evolutionary studies and personalized-medicine applications.

Methodology:

Employs algorithms that use phasing information to distinguish haplotypes during polishing and integrates short-read and long-read data to correct errors characteristic of Pacific Biosciences and Oxford Nanopore sequencing, producing haplotype-consistent consensus sequences.
