-c, --consensus-type <type>: 指定共识序列的类型,可以是most_frequent(默认),majority,all等。 -r, --region <region>: 指定要处理的基因组区域(例如chr1:1000-2000)。 -s, --samples <list>: 指定要包含的样本(以逗号分隔)。4...
I noticed something similar. Some regions get lost, but when I use-R <(grep 'chr1' chr1.region.bed)or-R <(cat chr1.region.bed), the missed regions are considered. I noticed the odd behavior when runningbcftools mpileup. Tried version 1.8 and 1.15.1. The behavior is similar. ...

New--regions-overlapand--targets-overlapoptions which address a long-standing design problem with subsetting VCF files by region. BCFtools recognize two sets of options, one for streaming (-t/-T) and one for index-gumping (-r/-R). They behave differently, the first includes only records ...
If a read is mapped to an incorrect region in a reference genome, then a false-positive cannot be fixed by the adjustment of an alignment. Since mis-mappings are presumably more abundant at repeats, we believe that the higher number of false positives from GATK HaplotypeCaller is, in a ...
