**What it does**

Creates quality statistics report for the given Solexa/FASTQ library.

.. class:: infomark

**TIP:** This statistics report can be used as input for **Quality Score** and **Nucleotides Distribution** tools.

-----

**The output file will contain the following fields:**

* column    = column number (1 to 36 for a 36-cycles read Solexa file)
* count   = number of bases found in this column.
* min     = Lowest quality score value found in this column.
* max     = Highest quality score value found in this column.
* sum     = Sum of quality score values for this column.
* mean    = Mean quality score value for this column.
* Q1    = 1st quartile quality score.
* med    = Median quality score.
* Q3    = 3rd quartile quality score.
* IQR    = Inter-Quartile range (Q3-Q1).
* lW    = 'Left-Whisker' value (for boxplotting).
* rW    = 'Right-Whisker' value (for boxplotting).
* A_Count    = Count of 'A' nucleotides found in this column.
* C_Count    = Count of 'C' nucleotides found in this column.
* G_Count    = Count of 'G' nucleotides found in this column.
* T_Count    = Count of 'T' nucleotides found in this column.
* N_Count = Count of 'N' nucleotides found in this column.
