@TIP_AND_WARNING@

**Tool Description**

The tool performs a one sample t-test for each feature.
Two options are available for the t-test: if the user provides the Group/Treatment variable, then the mean for each treatment condition is compared with Mu, the user-specified value of the true mean under the null hypothesis.
If Group/Treatment is not provided, then the mean across all samples is compared to Mu.

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

**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 [Optional]**

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

**Mu**

        - The value of the mean under the null hypothesis. Default = 0.


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

**Output**

The tool produces three outputs:

(1)  a TSV file with the results table containing p-values for each test and the corresponding differences between the group means and the mu value under the null.
(2) a TSV file containing indicator flags equal to 1 if the difference between the groups and the mean under the null is statistically significant using the indicated α levels.
(3) a PDF file with volcano plots for visual inspection of the differences between the group means and p-values. The red dashed line in the volcano plot(s) corresponds to a p-value = 0.01 cutoff (2 on the negative log base 10 scale).
