Hello, I do HaplotypeCaller twice,then compared the result vcf files with notepad++ plugin Compare.I found some different value about the QD annotation:

java -Xmx12G -jar $gatk -T HaplotypeCaller -R $fasta -I $data/sra/SRR948862/SRR948862.recal.bam -D $dbsnp --genotyping_mode DISCOVERY -o $data/sra/SRR948862/SRR948862.vcf -nct 12
-nct 12 : 12 threads,bigger than one!!!

we know QD=QUAL/AD(https://software.broadinstitute.org/gatk/documentation/tooldocs/current/org_broadinstitute_gatk_tools_walkers_annotator_QualByDepth.php),but they all wrong,and right with same value.
