VCF to GDS workflow converts VCF or BCF files into Genomic Data Structure (GDS) format. GDS files are required by all workflows utilizing the GENESIS or SNPRelate R packages.

Step 1 (VCF to GDS) converts VCF or BCF files (one per chromosome) into GDS files, with option to keep a subset of Format fields (by default only GT field). (BCF files may be used instead of VCF.)

Step 2 (Unique Variant IDs) ensures that each variant has a unique integer ID across the genome.

Step 3 (Chec
