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 can be viewed in tabular format in the Structural Variation view. This view is only available for reference-guided assemblies in .assembly format.
To access the Structural Variation view, choose a contig from the Explorer panel. Then either choose View > Structural Variation > (Contig Name) or click on the Show Table of Structural Variants tool ().
For definitions of each data column, as well as instructions for showing, hiding, renaming or rearranging data columns, see Choosing and understanding Structural Variation view columns.
