Registration Open for Bioc2024 July 24-26


This is the development version of VCFArray; for the stable release version, see VCFArray.

Representing on-disk / remote VCF files as array-like objects

Bioconductor version: Development (3.20)

VCFArray extends the DelayedArray to represent VCF data entries as array-like objects with on-disk / remote VCF file as backend. Data entries from VCF files, including info fields, FORMAT fields, and the fixed columns (REF, ALT, QUAL, FILTER) could be converted into VCFArray instances with different dimensions.
