# DRAGEN Report

DRAGEN Reports is an HTML report that provides a quick overview of the quality of an E2E analysis. The report consists of three sections, which are displayed as tabs in the report. The following sections describe the tabs.

### **Plate QC**

This section is subdivided into the following subsections:

* **Reagent Lot Summary:** This table describes the reagents used per plate in the analysis.
* **Plate QC Summary:** This table provides the plate level metrics, including *Calibration % in Tails, QC % in Tails, Reference Correlation,* and *Blank Background* metrics.
* **Calibration Scale Factors:** This histogram illustrates the distribution of calibration scale factors for a given plate.
* **QC Scale Factors:** This histogram illustrates the distribution of QC scale factors for a given plate.

### **Sample QC**

This section of the report contains information on which samples passed or flagged specifications as well as SOMAmer count yield per sample. It is subdivided into the following subsections:

* **Sample QC Summary:** The table describes the percentage of samples (organized by sample type) that passed Quality Control.
* **QC Summary:** The heatmap shows the QC status of samples based on their position in the plate wells.
* **Flagged Samples:** The table identifies samples that failed one or more sequencing or normalization specifications.
* **SOMAmer Read Counts:** This graph represents the SOMAmer count for each sample included in the analysis.

### **Specification**

This report section details the QC metrics and normalization steps.
