From the developer:
inGAP-sv is a structural variation detection and visualization app. The tool can refine short-read alignment by re-aligning short reads around a putative SV. In addition, it can detect large-size structural variations using paired-end sequencing reads. Further, it allows you to visualize SAM-formatted alignments and SVs.
You may want to check out more Mac applications, such as Genealogy Pro, sciatrope or Curvus Pro X, which might be related to inGAP.
