Table 3 Effect of read-depth and genotype quality (GQ) thresholds on the accuracy of GBS genotype calls

From: Low-depth genotyping-by-sequencing (GBS) in a bovine population: strategies to maximize the selection of high quality genotypes and the accuracy of imputation

Dataset ID Filtering criteria (first step) Number of variants Markers shared with SNP50 Number of calls examined Estimated accuracy (%)a

3 ≥4 reads 146,936 956 14,552 95.3
