BGEN reader documentation¶
BGEN is a file format for storing large genetic datasets. It supports both unphased genotypes and phased haplotype data with variable ploidy and number of alleles. It was designed to provides a compact data representation without sacrificing variant access performance.
This is a low-memory footprint library that provides an easy-to-use C interface to efficiently read BGEN files. It fully supports all the BGEN format specifications: 1.2 and 1.3; as well as their optional compressed formats.
