This tool creates summary statistics on a FASTQ file. 

.. class:: infomark

**TIP:** This statistics report can be used as input for the **Boxplot** 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).
* outliers    = Scores falling beyond the left and right whiskers (comma separated list).
* 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.
* Other_Nucs  = Comma separated list of other nucleotides found in this column.
* Other_Count = Comma separated count of other nucleotides found in this column.
