BQSR Bootstrap: Combine hard-filtered SNP and Indel VCFs?
I'm trying to run BQSR on mouse WES tumor-normal data according to [1-6]. I'm on the first round of bootstrapping a
knownSites.vcf to use for BQSR. I have just separated raw SNP and Indel variants from the
rawVariants.vcf produced by HaplotypeCaller and hard filtered both into
knownIndelSites1.vcf according to . My question is this: do I run BaseRecalibrator with just one of the
knownSites.vcf files (SNP or Indel)? Do I combine them? Do I run
BaseRecalibrator and just use two instances of
I tried searching but couldn't find an exact answer. Thanks in advance.
