We have data from target sequencing genes (only targeted two genes). We analyzed the data by GATK pipeline. Since the data set is too small, we tried hard filtration on both SNP and indels. At the same time, we sequenced the same sample by whole exome sequencing and filter SNP by VQSR. The quality of VQSR results is much better than hard filtration results. For economic reason, we need to develop analysis pipeline for target sequencing, is it ok to incorporate the target sequencing data into an exome sequencing data (merge the VCF files), do VQSR? I just worried the true sites in target sequencing data have different features compared to true sites in whole exome sequencing data.
