Genotype calling accuracy with Birdseed algorithm. a-d. Genotype calls determined using 198 samples with over 86% QC criteria were used as a reference. The average overall call rate for the 4 sets of the 12 samples were determined with 7 different sample sizes; 12 samples, 24 samples, 36 samples, 48 samples, 72 samples, 96 samples and 198 samples. The average concordance rates for the 4 sets of 12 samples were determined by comparison with the reference genotype calls. A negative correlation with a P value of 0.0053 and a positive correlation with a P value of 0.0115 were shown for overall call rate and concordance rate by fitting the power-law distribution to the data with least-squares approximation.
