I am using GATK 4. x, a new approach was introduced, which decoupled the two internal processes that previously composed variant calling: (1) the initial per-sample collection of variant context statistics and calculation of all possible genotype likelihoods given each sample by itself, which require access to the original BAM file reads and is If true, don't emit genotype fields when writing vcf file output. However, guidance from the GATK website for such filtering discusses filtering by many parameters that are not present in GVCF files Hello Genevieve,. My vcf file is 3TB heavy, and it makes absolutely no sense to produce another 3TB file with VariantFiltration, and only then use SelectVariants to exclude the variants marked by VariantFiltration. --version: false: display the version number for this tool: Optional Common Arguments--add-output-sam-program A VCF file to convert to a table. Upon completion, you will see many VCF file (2239 total) and its associated index files (idx) Next step is to merge and perform filtering on these variants to use them to re-calibrate the bam files. 4. 11. Could you please explain me, how I can check whether VariantFiltration is applied for my data?
