Filter out reads with low mapping qualities for HaplotypeCaller
This filter is applied by default for HaplotypeCaller and is designed to ensure that only reads that are likely to be informative will be used in the reassembly process. It performs the same basic function as the regular MappingQualityFilter, but it is used at specific points in the operation of HC where it is helpful to be able to apply a different quality threshold from the general case.
java -jar GenomeAnalysisTk.jar \ -T HaplotypeCaller \ -R reference.fasta \ -I input.bam \ -o output.vcf \ -mmq 10
Note that the HCMappingQuality filter itself does not need to be specified in the command line because it is set automatically for HaplotypeCaller.
