Fig. 1From: Breed-specific reference sequence optimized mapping accuracy of NGS analyses for pigsComparison of mapping ratio (%), coverage (X) and CPU time cost (s) among the three alignment strategies. The three alignment strategies were based on three references with different genetic relationships to samples, i.e., the commonly used reference sequence (CU-ref), the breed-specific reference sequence (BS-ref) and the sample-specific reference sequence (SS-ref)Back to article page
