Technical Abstract: Several classes of Structural Variants (SV) remain difficult to detect within sequenced genomes. Deletions and tandem duplications may affect a large proportion of variable genomic sequence space, yet their detection is still difficult to discern from false positive signals. Here, we present a method for detecting such variants from short-read sequence data using the orientation and distance of paired-end, and split-read mappings in addition to using read-depth as a filtering agent. We test our data using simulated SVs and find that our method is 27.5 times more precise than a competing detection program in detecting tandem duplications. Our method is also able to detect three times the number of deletions than the competition. This high degree of precision should enable better functional prediction of SVs from short-read sequence data.
