# Variant visualization tool

The **Variant visualization tool** in Emedgene is based on the [Integrative Genomics Viewer (IGV)](http://software.broadinstitute.org/software/igv/home). It provides a high-resolution, interactive genomic view for variant interpretation.

A customizable, [IGV](http://software.broadinstitute.org/software/igv/home)-based viewer enables visual review of alignment and annotation data for validating and interpreting variant calls.

The viewer is embedded in the [**Visualization tab**](/emedgene/emedgene-analyze-manual/variant_page/visualization_section.md) of the **Variant page** and is accessible from the [**Analysis tools tab**](https://github.com/illumina-swi/emedgene-docs/blob/prod/docs/emedgene-analyze-manual/reviewing_a_case/analysis-tools-tab/analysis-tools-tab-beta-v100.39.0+) in **New mode** (v100.39.0+).

## Popup visualization window (v100.40.0+)

In v100.40.0+, you can open the variant visualization tool in a separate window to support flexible review, including multi-monitor workflows.

* To open the visualization tool in a new window, select **Open in popup** in the top navigation panel. The visualization is moved from the original page into the popup window, and the embedded visualization is hidden.
* Navigating between variants continues to update the visualization in real time.
* Closing the popup returns the visualization to the original page.

Use the tool to review sequencing alignments, population data, functional predictions, curated annotations, and other supporting evidence in genomic context.

The visualization tool supports SNVs, indels, CNVs, STRs, and variants called with DRAGEN MRJD caller or DRAGEN Targeted caller.

## v100.40.0+

In v100.40.0 and newer:

* The **Variant visualization tool** is accessible from the [**Visualization tab**](/emedgene/emedgene-analyze-manual/variant_page/visualization_section.md) on the **Variant page** and from the [**Analysis tools tab**](https://github.com/illumina-swi/emedgene-docs/blob/prod/docs/emedgene-analyze-manual/reviewing_a_case/analysis-tools-tab/analysis-tools-tab-beta-v100.39.0+) in **New mode**.
* The improved [**Track Manager**](/emedgene/emedgene-analyze-manual/variant-visualization/variant-visualization-tool/track-manager-v100.40.0+.md) lets you control which tracks are displayed and their order, and reset your view to your organization defaults.
* More [visualization tracks](/emedgene/emedgene-analyze-manual/variant-visualization/variant-visualization-tool/visualization-tracks.md) are available.
* You can open the **Variant visualization tool** in a popup window.

## v100.39.0 and older

In v100.39.0:

* The **Variant visualization tool** is accessible from the [**Visualization tab**](/emedgene/emedgene-analyze-manual/variant_page/visualization_section.md) on the **Variant page** and from the [**Analysis tools tab**](https://github.com/illumina-swi/emedgene-docs/blob/prod/docs/emedgene-analyze-manual/reviewing_a_case/analysis-tools-tab/analysis-tools-tab-beta-v100.39.0+) in **New mode**.

In v100.39.0 and older:

* [**Track Manager**](/emedgene/emedgene-analyze-manual/variant-visualization/variant-visualization-tool/viewing-modes.md) lets you control which tracks are displayed, individually and by category.
