WebHaplotypeCaller is used to call potential variant sites per sample and save results in GVCF format. With GVCF, it provides variant sites, and groups non-variant sites into blocks during the calling process based on genotype quality. This is a way of compressing the VCF file without losing any sites in order to do joint analysis in subsequent steps.
