 Delly is an integrated structural variant (SV) prediction method that can discover, genotype and visualize deletions, tandem duplications, inversions and translocations at single-nucleotide resolution in short-read massively parallel sequencing data. It uses paired-ends, split-reads and read-depth to sensitively and accurately delineate genomic rearrangements throughout the genome. Structural variants can be annotated using [Delly-sansa](https://github.com/dellytools/sansa) and visualized using [Delly-maze](https://github.com/dellytools/maze) or [Delly-suave](https://github.com/dellytools/suave).
