Web5.1 Brief introduction. HaplotypeCaller 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 ... WebHaplotypeCaller is the focal tool within GATK4 to simultaneously call germline SNVs and small Indels using local de novo assembly of haplotype regions. Algorithm. Briefly, the HaplotypeCaller works by: 1. Identify active regions or regions with evidence of variations. 2. Re-asssemble the active regions.
