Objective:

To address the challenge of distinguishing true genetic variation from sequencing errors in genome assembly using an AI-based tool.

Approach:
    Key Findings:
    • Corrected sequencing reads showed substantially lower error rates across mismatches, insertions, and deletions compared to uncorrected reads.
    • HERRO produced more contiguous genome assemblies and enabled reconstruction of complete human chromosomes, including the X and Y chromosomes.
    • Similar improvements in assembly quality were observed in zebrafish, fruit flies, and thale cress.
    Interpretation:

    Higher-quality genome maps can improve detection of structural variants and support precision medicine research.

    Limitations:
    • Some highly repetitive genomic regions remain challenging.
    • The method requires substantial computational resources.
    Conclusion:

    HERRO enables high-quality genome assemblies from a single long-read sequencing workflow, potentially simplifying genome assembly processes.
