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](https://help.connected.illumina.com/emedgene/emedgene-analyze-manual/settings/organization_settings_-330+/kit-management).\
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.
