# Sequencing information

## **Select a coverage BED**

<div align="left"><figure><img src="/files/JcyTHDXAY2lXURafc5rh" alt="" width="563"><figcaption></figcaption></figure></div>

A coverage BED[^1] file is used to calculate and determine quality control (QC) metrics for your case. This file defines the genomic regions that should meet coverage requirements during sequencing.

{% hint style="info" %}
BED files defining custom kits can be added in Organization settings > [Kit management](/emedgene/emedgene-analyze-manual/settings/organization_settings_-330+/kit-management.md).\
Furthermore, the BED file chosen here is linked to a **PON (Panel of Normals) file** when starting from FASTQs and conducting CNV calling.
{% endhint %}

After selecting a coverage BED file, the available reference sequences for this kit will be displayed.

## **Specify sample preparation details**

Specify details such as laboratory name, sequencing machine used, sequencing reagent kit, and expected coverage.

This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## 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/launching-analysis/creating_a_single_case/3.-case-info/sequencing-information.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.
