I apologize if it is too simple question but I got stuck here. Here is the situation:

I have exome data 32 patients. My aim is to identify unique somatic mutations in each patients. For this I have completed my pipeline for Whole Exome Data analysis using various tools like BWA mem, picard, gatk etc. Now I have VCF and gVCF file of each patient. For Variant Quality Score recalibration (VQSR), as per the doccumentation, we should have at least 30 patient data for good recalibration. So in order to perform VQSR, I combined gVCF of all 32 patients using genotypeGVCFs tool of gatk and done with VQSR. But now I have cohort of all patient data (a large combined vcf file). How to get all vcf file for each patient (by not missing a single variant associated to that patient) because I don't know how variant sub-class tool or other extraction tool work to extract all of the unique and related features to each patient. I know how to get significant mutations using mutect but here it is combined file but I want to get it for each one individually. I need suggestions. Thanks.
