VariantRecalibrator across multiple VCFs with identical positions but different annotations
I have a set of VCFs with identical positions in them:
1 10097 . T . 26 . AN=196;DP=1622;MQ=20.06;MQ0=456 GT:DP
1 10097 . T . 21.34 . AN=198;DP=2338;MQ=19.53;MQ0=633 GT:DP
1 10097 . T . 11.70 . AN=240;DP=3957;MQ=19.74;MQ0=1085 GT:DP
1 10097 . T . 15.56 . AN=134;DP=1348;MQ=18.22;MQ0=442 GT:DP
If I use all of them as input for VariantRecalibrator, which annotations will VariantRecalibrator use? Should I instead merge the VCFs with CombineVariants and run VariantAnnotator, before I run VariantRecalibrator?
I'm not sure if the forum is for asking technical questions only or you are allowed to ask for best practices as well. Feel free to delete my question, if it doesn't belong here. Thank you.
