# vcflib ### A C++ library for parsing and manipulating VCF files. [](https://github.com/vcflib/vcflib/actions?query=workflow%3ACI) [](https://travis-ci.com/github/vcflib/vcflib) [](https://anaconda.org/bioconda/vcflib) [](https://anaconda.org/bioconda/vcflib) [](https://github.com/brewsci/homebrew-bio) [](https://www.gnu.org/software/guix/packages/V/) [](https://packages.debian.org/testing/libvcflib-dev) [](https://www.cprogramming.com/c++11/what-is-c++0x.html) [](https://matrix.to/#/#vcflib:matrix.org) Vcflib and related tools are the workhorses in bioinformatics for processing the VCF variant calling format. See Vcflib and tools for processing the VCF variant call format; Erik Garrison, Zev N. Kronenberg, Eric T. Dawson, Brent S. Pedersen, Pjotr Prins; doi: https://doi.org/10.1101/2021.05.21.445151 ## overview The [Variant Call Format (VCF)](http://www.1000genomes.org/wiki/Analysis/Variant%20Call%20Format/vcf-variant-call-format-version-41) is a flat-file, tab-delimited textual format that describes reference-indexed variations between individuals. VCF provides a common interchange format for the description of variation in individuals and populations of samples, and has become the *de facto* standard reporting format for a wide array of genomic variant detectors. vcflib provides methods to manipulate and interpret sequence variation described by VCF. It is both: * an API for parsing and operating on records of genomic variation as it can be described by the VCF format * a collection of command-line utilities for executing complex manipulations on VCF files vclib is both a library (with an API) and a collection of useful tools. The API provides a quick and extremely permissive method to read and write VCF files. Extensions and applications of the library provided in the included utilities (*.cpp) comprise the vast bulk of the library's utility. --- Short index: - [Install](#INSTALL) - [Usage](#USAGE) - [TOOLS](#TOOLS) * [Filter](#filter) * [Metrics](#metrics) * [Phenotype](#phenotype) * [Genotype](#genotype) * [Transformation](#transformation) * [Statistics](#statistics) * [Scripts](#scripts) - [Link library](#link-library) - [Build from source](#build-from-source) - [Development](#Development) - [LICENSE](#LICENSE) - [Credit work](#Credit) --- ## INSTALL For latest updates see [RELEASE NOTES](./RELEASE_NOTES.md). ### [Bioconda](https://bioconda.github.io/user/install.html) Conda installs in user land without root access ```sh conda install -c bioconda vcflib ``` ### [Homebrew](https://brew.sh) Homebrew installs on Linux and Mac OSX ```sh brew install brewsci/bio/vcflib ``` ### [Debian](https://debian.org/) For Debian and Ubuntu ```sh apt-get install libvcflib-tools libvcflib-dev ``` ### [GNU Guix](https://guix.gnu.org/) We develop against guix and vcflib is packaged as ```sh guix package -i vcflib ``` See also the Guix shell below. ## USAGE Users are encouraged to drive the utilities in the library in a streaming fashion, using Unix pipes to fully utilize resources on multi-core systems. Piping provides a convenient method to interface with other libraries (vcf-tools, BedTools, GATK, htslib, [bio-vcf](https://github.com/vcflib/bio-vcf), bcftools, [freebayes](https://github.com/freebayes)) which interface via VCF files, allowing the composition of an immense variety of processing functions.

Note, if you have an existing repo update submodules with ```sh git submodule update --init --recursive --progress cd build cmake --build . --target clean ``` Build dependencies can be viewed in the Travis-CI and github-CI scripts (see badges above), as well as [guix.scm](./guix.scm) used by us to create the build environment (for instructions see the header of guix.scm). Essentially: - C++ compiler - htslib - tabixpp For include files add - libhts-dev - libtabixpp-dev - libtabixpp0 And for some of the VCF executables - python - perl ### Using a different htslib Check out htslib in tabixpp (recursively) and cmake -DHTSLIB_LOCAL:STRING=./tabixpp/htslib/ .. cmake --build . ## link library The standard build creates `build/vcflib.a`. Take a hint from the [cmake](./CMakeLists.txt) file that builds all the vcflib tools. ## source code See [vcfecho.cpp](./src/vcfecho.cpp) for basic usage. [Variant.h](./src/Variant.h) and [Variant.cpp](./src/Variant.cpp) describe methods available in the API. vcflib is incorporated into several projects, such as [freebayes](https://github.com/freebayes/freebayes), which may provide a point of reference for prospective developers. Note vcflib contains submodules (git repositories) comprising some dependencies. A full Guix development environment we use is defined [here](./guix.scm). # adding tests vcflib uses different test systems. The most important one is the [doctest](https://docs.python.org/3/library/doctest.html) because it doubles as documentation. For an example see [vcf2tsv.md](./test/pytest/vcf2tsv.md) which can be run from the command line with ```sh cd test python3 -m doctest -o NORMALIZE_WHITESPACE -o REPORT_UDIFF pytest/vcf2tsv.md ``` # Contributing To contribute code to vcflib send a github pull request.
