# Prerequisites for accessing the DRAGEN QC report

## NGS case

### **Option 1: FASTQ case**

{% stepper %}
{% step %}
Run a FASTQ case in Emedgene.
{% endstep %}

{% step %}
Since DRAGEN analysis is integrated into Emedgene secondary analysis pipeline, QC reports are automatically generated in the system.
{% endstep %}
{% endstepper %}

### **Option 2: VCF case**—**Bring your own DRAGEN (BYOD)**

{% stepper %}
{% step %}
Run DRAGEN analysis externally.
{% endstep %}

{% step %}
[Prepare](/emedgene/emedgene-analyze-manual/reviewing_a_case/lab_tab/sample-quality-section/dragen-qc-report/prerequisites-for-accessing-the-dragen-qc-report/how-to-i-prepare-metrics-files-generated-by-dragen-to-be-used-as-input-for-emedgene.md) a TAR archive containing DRAGEN QC metrics files.
{% endstep %}

{% step %}
Upload the TAR archive and the sample VCF file to Emedgene.
{% endstep %}
{% endstepper %}

{% hint style="info" %}
This workflow is only supported for [batch case upload via UI and CLI](/emedgene/emedgene-analyze-manual/launching-analysis/creating_multiple_cases.md) and [API-based case creation](/emedgene/integrations/api-beginner-guide.md).
{% endhint %}

## Array case

Array cases start from VCF input files. DRAGEN QC for array cases is supported on Emedgene v100.39.0 and later.

### **VCF case**—**Bring your own DRAGEN (BYOD)**

{% stepper %}
{% step %}
Run DRAGEN analysis externally using [DRAGEN Array v1.3.0](https://help.dragenarray.illumina.com/reference/release-notes/dragen-array-v1.3.0-release-notes).
{% endstep %}

{% step %}
Upload the `.annotated_cyto.json` DRAGEN QC metrics file, the sample VCF file, and the `.gt_sample_summary.json` file to Emedgene.
{% endstep %}
{% endstepper %}
