 Delly2 is an integrated structural variant prediction method that can discover and genotype deletions, tandem duplications, inversions and translocations
 at single-nucleotide resolution in short-read massively parallel sequencing data. It uses paired-ends and split-reads to sensitively and accurately
-delineate genomic rearrangements throughout the genome. Structural variants can be visualized using [Delly-maze](https://github.com/tobiasrausch/delly/tree/master/vis/README.md) and [Delly-suave](https://github.com/tobiasrausch/delly/tree/master/vis/README.md).
