DCHap

DCHap performs haplotype phasing of long, error-prone reads from third-generation sequencing platforms, including PacBio SMRT and Oxford Nanopore Technologies, to reconstruct haplotypes for genetic analyses.

Key Features:

• Divide-and-Conquer Algorithm: Employs a divide-and-conquer strategy that partitions the phasing problem into subproblems to handle long reads and manage TGS errors.
• Accuracy and Scalability: Benchmarked against state-of-the-art phasing tools, it achieves comparable or superior accuracy measured by switch errors and scales with increasing read length and coverage.
• Compatibility with TGS Platforms: Optimized for third-generation sequencing data from PacBio SMRT and Oxford Nanopore Technologies, accommodating long-read characteristics and higher per-read error rates.

Scientific Applications:

• Haplotype reconstruction: Reconstructs the two parental chromosome copies (haplotypes) from an individual's sequencing reads.
• Disease association and personalized medicine: Supports analyses linking genetic variation to disease susceptibility and applications in personalized medicine and complex genetic disorder studies.
• Downstream genomic analyses: Provides phased haplotypes for downstream variant calling, association studies, and population genetics research.

Methodology:

Uses a divide-and-conquer phasing algorithm that breaks the phasing problem into manageable subproblems to improve computational efficiency and mitigate errors inherent in TGS reads.
