Hi all, I have a 4 exome experiment (high coverage). According to best practices I can't apply VQSR, so I must filter on SNP properties. One thing is not clear: should all the option apply? In other words should I select using boolean "and" (i.e. QD  < 2.0 & MQ < 40.0 & FS > 60.0 & HaplotypeScore > 13.0 & MQRankSum < -12.5 & ReadPosRankSum < -8.0 for SNP) or "or" (i.e. QD  < 2.0 | MQ < 40.0 | FS > 60.0 | HaplotypeScore > 13.0 | MQRankSum < -12.5 | ReadPosRankSum < -8.0 for SNP)?
