# Launching the Chromosome View

The *Chromosome view* can be invoked from some data nodes on the *Analyses* tab, giving a global overview of the results; or from certain *Task report* or result pages, providing a focused view, i.e. pointing to a specific feature of interest.

## Running a Chromosome View Task from a Data Node <a href="#launchingthechromosomeview-runningachromosomeviewtaskfromadatanode" id="launchingthechromosomeview-runningachromosomeviewtaskfromadatanode"></a>

On the *Analyses* tab, selecting a data node containing aligned reads, variants, or feature lists, shows *Chromosome view* in the *Exploratory analysis* section of the context-sensitive menu.

If Connected Multiomics has no information on the genome build for the data, you will need to provide the species and genome build in a subsequent dialog (not shown). Otherwise, chromosome view will come up directly.

A new *Chromosome view* task node will be added to the task graph. To invoke the viewer, **double-click** on the node (you can also select it and then go to **Task report** in the menu). When invoked in this way, the default visualization in the *Chromosome view* is the first 100,000 bases of the first chromosome.

## Browsing directly to a location directly from a Task Report <a href="#launchingthechromosomeview-browsingdirectlytoalocationdirectlyfromataskreport" id="launchingthechromosomeview-browsingdirectlytoalocationdirectlyfromataskreport"></a>

Another way to get the *Chromosome view* is through a *Task report*. You can launch the viewer by selecting the **chromosome icon** ![](/files/zNlcDs7dGUIiZWjWLMZy) in the View column of differential test report or *View Variants* reports. In that case, the *Chromosome view* will browse directly to the selected genomic location (i.e. a transcript or a variant, depending on the analysis pipeline).

Depending on the task report used to invoke the *Chromosome view* was invoked, some tracks may be pre-selected and customized. For example, when invoked from a variant table, the reads histogram track will be colored by bases (rather than the default of coloring by sample).

# Agent Instructions: Querying This Documentation

If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter:

```
GET https://help.multiomics.illumina.com/icm/analyses/analysis-functionality/data-viewer/chromosome-view/launching-the-chromosome-view.md?ask=<question>
```

The question should be specific, self-contained, and written in natural language.
The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
