SVvalidation: A long-read-based validation method for genomic structural variation.

Area of Science:

• Genomics
• Bioinformatics
• Computational Biology

Background:

• Accurate detection of structural variations (SVs) in genomic sequences is crucial for understanding genetic diseases.
• Existing SV detection tools often yield high false positive rates, necessitating robust validation methods.
• Current SV validation techniques lack sufficient accuracy and efficiency.

Purpose of the Study:
