SNP calling failure rate in association with DLR. SNP calling data were extracted from a. Agilent 180 K aCGH/SNP array, and b. Agilent 400 K aCGH/SNP array. SNP calling failure rate increased significantly when DLR is greater than 0.2 (**, p < 0.01). No significant difference (NS) between samples of DLR 0.2–0.3 and DLR > 0.3
