**What it does**

This tool generates a distribution of peaks with respect to their distance from TSS.

.. class:: warningmark

This tool requires at least 1 numerical column **"distance from TSS"**.

-----

**Syntax**

- All invalid, blank and comment lines in the query are skipped.  The number of skipped lines is displayed in the resulting history item.
- **Numerical column for x axis** - only numerical columns are possible.
- **Number of breaks(bars)** - breakpoints between histogram cells. Value of '0' will determine breaks automatically.
- **Plot title** - the histogram title.
- **Label for x axis** - the label of the x axis for the histogram.
- **Zoom visualization** - Limit of the X axis. All the peaks falling beyond this limit are plotted in the last histogram cell. 
- **Include smoothed density** - if checked, the resulting graph will join the given corresponding points with line segments.

-----

**Example**

- Input dataset ann_file from GIN (twelve columns: c1, c2, c3, c4, c5... c12):

.. image:: static/images/CARPET/output_ann.png


- Chose column **c12** ("Distance TSS").
