Hey, has anyone worked with two steps of VQSR (i.e. the successive application of VariantRecalibrator and ApplyRecalibration) for the non-human genomes?

You know, the human genome data have good truth and known resource datasets (HapMap
, Omni
, 1000G,
 which are already available for VQSR analysis. However, I do not have idea how to do it with mouse genome because I need to generate my own resource set. Anyone has experiences on this?

I did HARD SNP variant filtering using VariantFiltration of GATK since my variant file was produced by UnifiedGenotyper. Is VQSR unnecessary and I can skip this step since it looks a little challenge to me?

Thank you,

Skip it - even Broad is not doing VQSR regularly
