tSNPs. Illumina utilizes their proprietary GenCall data analysis software to ascertain quality and reliability of the genotypes called. A 10% GenCall score (i.e. the 10th percentile rank for all GenCall scores of the study samples at a given locus) greater than 0.7 is considered accurate and high-quality genotype data. The mean 10% GenCall scores for the 12 CNR1 tSNPs is 0.89 (SD=0.05; Range=0.80 – 0.96).
