This script analyzes variant call format (VCF) files to identify genetic variants shared across multiple samples. Given a list of VCF paths, it reports variants present in ≥10-100% of samples (10% increments), showing chromosome, position, alleles, sample count, and percentage. Processes genotype data to ensure accurate variant presence detection
