@TIP_AND_WARNING@

**Tool Description**

The tool performs Kruskal-Wallis non-parametric test, an analog of the one-way ANOVA F-test that does not rely on the normality assumption of the distribution.
Unlike t-tests or an ANOVA F-test, a Kruskal-Wallis test is based on ranks where ranks are compared between groups.
The test is performed (1) for samples from all groups together and (2) for the samples belonging to each group.
The user is referred to the literature for more details on the Kruskal-Wallis test and the computation/approximation of corresponding p-values.

--------------------------------------------------------------------------------

**Input**

    - Two input datasets are required.


@WIDE@

**NOTE:** The sample IDs must match the sample IDs in the Design File
(below). Extra columns will automatically be ignored.

@METADATA@

@UNIQID@

**Group/Treatment**

        - Name of the column the Design File that contain group classifications.

--------------------------------------------------------------------------------

**Output**

Three different outputs are generated:

(1) a TSV file with the results, including p-values for each test and the corresponding differences between the means for comparisons between the groups.
(2) a TSV file containing indicator flags.  A flag = 1 if the difference between the groups is statistically significant.
(3) a PDF file with volcano plots for visual inspection of the differences between the treatment groups. The red dashed line in the volcano plot(s) corresponds to a 0.01 cutoff for p-values (2 on the negative log base 10 scale).
