# Combine 5-base methylation and variant data

The *Combine 5-base methylation and variant data* task enables users to combine annotated differentially methylated regions (DMRs) and annotated variants, for dual-omics insights in DNA Methylation Prep data analysis.

## Running Combine 5-base methylation and variant data

The *Combine 5-base methylation and variant data* task expects annotated DMRs and annotated variants data within the same analysis. This task can be invoked at either *Annotated regions* data node or *Annotated variants* data node.

* Click **Annotated regions** or **Annotated variants** data node.
* Click **Combine multiomics data** section in the context-sensitive task menu.
* Click **Combine 5-base methylation and variant data**.
* Click **Select data node** to select another data node (*Annotated variants* or *Annotated regions*) for intersection or union.

* Data nodes that are selectable for combine are in blue. In example below, *Annotated regions* data node from the methylation analysis branch are selected.

* Select **intersection** or **union** to combine methylation and variant data, then click **Finish**.
  * Intersection: Use gene ID to intersect DMRs and variants. Every intersected variant and DMR will be reported in an individual row in task report.
  * Union: Report intersection (by gene ID) result and also variants that overlap DMR by specified distance (default is +/- 1000bp).

## Task output

When complete, double-click on **5-base methylation and variants** data node to open result. The task report is similar to the [Summarized cohort mutations](/icm/analyses/analysis-functionality/task-menu/variant-analysis/summarize-cohort-mutations.md) task report, with an additional column **Origin** to indicate if result in a row is present in both methylation and variant data (VC, DMR), or variant data only (VC), or methylation data only (DMR).

# 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.connected.illumina.com/icm/analyses/analysis-functionality/task-menu/combine-multiomics-data/combine-5-base-methylation-and-variant-data.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.
