File Formats


Group Logo

The Global Alliance Data Working Group File Formats Task Team are the custodians of the SAM/BAM, CRAM and VCF/BCF file formats. The File Formats Task team works on the specification, standardisation, and evolution of file formats for sequencing reads and variation data, and associated infrastructure such as index formats. The group includes representatives from the at least two primary implementations of the formats.
We welcome contributions and suggestions from the community. The primary mechanism for proposing additions or edits to the formats is via the hts-specs github repository by raising issues or pull requests. The group meets bi-monthly to review the specification proposals and additions.
