wgs-prs

End-to-end WGS to polygenic risk score pipeline. Takes paired-end FASTQ files (or a pre-existing VCF) through nf-core/sarek for variant calling, applies VCF QC (normalisation, hard filtering, Ti/Tv and Het/Hom checks), then computes polygenic risk scores via the PGS Catalog. Fills the FASTQ to VCF gap upstream of the gwas-prs skill.
