The post-call filtering is covered in more detail, split up into SNP and InDel sections. For example, to include only sites which have no filters set, use -f. All commands work transparently with both VCFs and BCFs, both As bcftools documentation states, the bcftools query command extracts specific fields from VCF or BCF files by applying specific filtering criteria, which finally outputs those fields in a user-defined format. REF = the reference allele. 6 Filter out variants for a variety of reasons. bcftools allows applying filters on many of its commands, but usually they are used with bcftools view or with bcftools filter. SITE ID ID = the SNP/indel id (blank for us, but SNPs in the human genome have ids). GRCh37/38), but chromosomal coordinates may differ! 10 . Users are now required to choose I have just transitioned from using vcftools to bcftools, and am curious about how my previous methods of filtering translate. My suggestion would be to add a feature in bcftools norm which could assign IDs on the fly.
