# Enabling visualization for a VCF case

**Loading local alignment files to your case in Emedgene.**

Visualization is automatically available for cases analyzed from **FASTQ** or **BAM** files. For cases analyzed only from **VCF files**, read alignment visualization can still be enabled by providing **alignment files** (BAM+BAI or CRAM+CRAI).

You can enable mapping visualization for a VCF case in three ways:

* **API-based case creation:** Define the location of alignment files directly in the JSON payload.
* **Batch upload:** Include the paths to visualization files in the input CSV when uploading cases in bulk.
* **Manual upload of local alignment files:**

1. Click the Load local file button on top of the Visualization section.
2. Select relevant alignment files stored on your PC.
3. Once uploaded, choose which samples to visualize by selecting their names from the top of the viewer.

## 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, and the optional `goal` query parameter:

```
GET https://help.connected.illumina.com/emedgene/emedgene-analyze-manual/variant-visualization/variant_visualization_setup/enabling_visualization_for_a_vcf_case.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

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.
