The bcftools/htslib VCF commands
HTSlib is a C library forhigh-throughput sequencing data formats. It is designed for speed and works with both VCF and BCFv2.
Download and installation
The library is hosted on github. It can be downloaded and compiled the usual way.The clone command is run only once, the pullcommand is run whenever the latest snapshots from github is needed.Please see the bcftools githubpage for the up-to-date version of the clone command. The software is under heavydevelopment and the option --branch may be required.
git clone [--branch=name] git://github.com/samtools/htslib.git htslib
git clone git://github.com/samtools/bcftools.git bcftools
cd htslib; git pull; cd ..
