- Variant Calling: _HaplotypeCaller_ in GVCF mode was used to call variants in each sample, which were then combined using _CombineGVCFs_ and genotyped with _GenotypeGVCFs_

- Variant Filter: variants were filtered using VariantFiltration based on their 'QualityByDepth (i.e., `--filter-expression 'QD < 2.0'`) and overall coverage 'DP' (i.e., `--filter-expression 'DP < 50'`), while to identify private variants belonging to each sample additional filters were applied, i.e., variants having low genotype quality (i.e., GQ < 80) and low coverage (i.e., DP < 100 stringent and DP < 10 relaxed, respectively) were removed
