Structural Variation view

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.

The table below describes tasks related to the Structural Variation view:

Task	How To
Open the Analysis view at the structural variation’s position	Double-click on any row in the table.
Add, rearrange, rename, or remove table columns	Press the Change options in this view tool () in the top right of the view. For instructions and a description of each column type, see Choosing and understanding Structural Variation view columns.
Choose which items should appear in the view	Press the Filter () tool in the top right of the view. See Filtering in the Structural Variation view for detailed information.
Export data from the table	Press the Export data tool () in the top right of the view. This opens a save dialog in which you can save the tabular data in comma-separated (.csv) or tab-separated (.tab) format. See Export data to a file for details.
Toggle between showing/hiding the table header	Use the Show quick details tool () in the top right of the view.
