Fail to apply --filterExpression of VariantFiltration
I tried to apply the following command to my raw vcf file to filter it with the command:
java -Xmx30g -jar ../GATK/GenomeAnalysisTK.jar -R ../ref.fa -T VariantFiltration --filterExpression " QD < 20.0 || ReadPosRankSum < -8.0 || FS > 10.0 || QUAL < $MEANQUAL || MQ <30.0 || DP< 10.0 " --filterName LowQualFilter --missingValuesInExpressionsShouldEvaluateAsFailing --variant ../s1.raw.vcf --logging_level ERROR -o ../s1.makered.raw.vcf
grep -v "Filter" s1.makered.raw.vcf >s1.flt.vcf
After that, I checked the result file s1.flt.vcf and found the following makered "PASS" .Obviously, the command doesn't work as ‘DP=8“ should be makered "LowQualFiter".
