# Colocation map mode (v100.41+)

From v100.41, whole genome TruPath cases with colocation data have a **Colocation map** mode on the [**Genome View** tab](/emedgene/emedgene-analyze-manual/reviewing_a_case/genome-overview.md). The colocation map shows which regions of the genome are physically close.

The mode shows this data for the whole genome as a two-dimensional map, in place of the ideogram and the data tracks. To open it, select **Colocation map** from the list at the top left of the tab.

* Scroll within the map to see all of it.
* To find a region of interest, enter a gene, a position, or another search term in the search box above the map.

The colocation data comes from a `.hic` file for the sample.

{% hint style="info" %}
DRAGEN server does not produce the `.hic` file by default. To get a conversion script, contact Illumina Bioinformatics Support.

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

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:

```
GET https://help.bioinsight.illumina.com/emedgene/emedgene-analyze-manual/reviewing_a_case/genome-overview/colocation-map-mode.md?ask=<question>&goal=<user_goal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.

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.
