In addition to variants and small insertions and deletions, genetic variation can also involve large scale rearrangements. These rearrangements may include large insertions and deletions, inversions, and translocations, collectively known as “structural variations” (SV’s).
During a templated data assembly with DNASTAR’s SeqMan NGen, potential insertions and deletions are coded as such in the assembly output. When the assembly project is opened in GenVision Pro, the encoded SV information for a selected sample can be viewed in tabular format in the Structural Variation view.
To create a table of structural variations:
- Select exactly one sample in the Experiments section of the Explorer panel. The sample must be an .assembly project that used a reference sequence.
- Within the Experiments section, click on the Show Table of Structural Variants tool (

); see image below. Alternatively, choose Variants > Show Table > Structural Variants in (experiment name). The Structural Variation view is automatically generated and becomes the active view.
