Production genotyping began on January 16, 2004 and the genotyping report files were delivered on March 5, 2004, a time span of 56 days from the receipt of DNA to data delivery. The files contained the DNA barcode ID, the locus ID, the genotypes, and the GenCall score for each genotype. As genotypes are designated by alleles A and B, an allele key file was provided with context sequence for each SNP and the designation for the nucleotides that represent alleles A and B.
