+**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):

+.. image:: ./static/fastx_icons/fastq_quality_boxplot_1.png
+
+
+A relatively good quality library (median quality degrades towards later cycles):
+
+.. image:: ./static/fastx_icons/fastq_quality_boxplot_2.png
+
+A low quality library (median drops quickly):
