WebBCFtools is a set of utilities that manipulate variant calls in the Variant Call Format (VCF) and its binary counterpart BCF. All commands work transparently with both VCFs and BCFs, both uncompressed and BGZF-compressed. Most commands accept VCF, bgzipped VCF and BCF with filetype detected automatically even when streaming from a pipe. WebThis function is helpful for creating subsets of VCF files or just removing unwanted variants from VCF files. To write out the variants that pass through filters use the --recode option. …
