**What it does**

Creates a boxplot graph for the quality scores in the library.

.. class:: infomark

**TIP:** Use the **FASTQ Statistics** tool to generate the report file needed for this tool.

-----

**Output Examples**

* Black horizontal lines are medians
* Rectangular red boxes show the Inter-quartile Range (IQR) (top value is Q3, bottom value is Q1)
* Whiskers show outlier at max. 1.5*IQR


An excellent quality library (median quality is 40 for almost all 36 cycles):

A relatively good quality library (median quality degrades towards later cycles):

A low quality library (median drops quickly):
