======================================================================================== nf-exomiser-pipeline (Cohort Merging & Local Exomiser Execution)

Pipeline Description:
1. Reads a samplesheet, validating that affected samples have HPO terms.
2. Merges all VCFs into a single cohort-wide VCF.
3. Filters the merged VCF, annotates de novo mutations, and splits it back into
   single-sample VCFs, annotating parental genotypes.
4. Filters for AFFECTED samples only.
5. The final annotated VCFs for affected samples are processed with Exomiser and VEP.
