bcftools 作为实用的变异查找工具, 可以查找指定区域的变异; 相比于GATK可以互相补充。 1. conda 安装 conda install bcftools -y 2. bcftools 查找变异位点 bcftools mpileup -r chr22:38519150-385191650\-f /public/analysis/reference/hg19/hg19.fa\-Ou Sample.sorted.bam|bcftoolscall-mv > chr22.vcf 3....

具体操作中，首先通过conda进行安装，确保软件环境准备就绪。接下来，利用bcftools功能查找变异位点，实现对目标区域的深入探索。在查找过程中，设置过滤参数成为关键步骤，它能够帮助我们根据特定条件筛选出高质量的变异位点，如特定的变异类型、频率或深度等。在使用bcftools过程中，详细参数如同mpileup一样，为...

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. ...
bcftools也可以进行SNP calling。...在之前的版本中,通常都是和samtools的mpileup命令结合使用, 命令如下 samtools mpileup -uf ref.fa aln.bam | bcftools view -bvcg -...> var.raw.bcf 由于samtools和bcftools更新得都很快,只要有一个版本不对,采用上面的pipeline就会报错。...为了减少版本不合适带来的问题,...
The indel boundaries are based on REF // (POS+1,POS+rlen-1). This is not entirely correct: mpileup likes to // output REF=CAGAGAGAGA, ALT=CAGAGAGAGAGA where REF=C,ALT=CGA could be // used. This filter is therefore more strict and may remove some valid // SNPs. ...
