# How to use the statistics GUI

In this section the statistics GUI is introduced.

## Run statistics.m

Zoom

Open statistics.m and click run.

## Start Screen

Zoom

This is the start screen of the statistics gui. The idea of the statistics gui is to visualize and inspect different combinations of subpopulations of your events. Panel 1 to 3 allows you to choose different combinations of databases, subpopulations and colors. Lets go through the different options.

## 1) Choose Database

In this panel you can load different event databases generated by the analysis GUI. Just click on Load database and choose the desired event database. Only event databases created by the analysis GUI or the scripts can be read.

## 2) Filter Options

The second panel lets you decide which subpopulations you want to visualize:

- Events that have been detected as being impulsions
- All events except impulsions
- Subpopulations based on their number of levels

## 3) Color Picker

The third panel lets you assign a color to the previously chosen settings. Just pick one of the predefined colors or enter an RGB code in the fields on the right hand. Please note that the values have to been between 0 and 1.The current color square shows you the currently selected color.

## 4) Filter List

Clicking on the Add your selection to the filter list button adds the combination of panels 1 to 3 to your filter list. If you want to delete an item from the list use the Delete from list button. The up-and down arrows allow reordering of the list and consequently change the look of the plots.

## Visualization

Zoom

In this example two settings have been chosen. The pink color corresponds to one-level events and the green color to two-level events. You can click on points of the scatter plot to visualize (1) the corresponding event. Selected dots are circled in red (2), whereas dots corresponding to other levels of the same event are circled in yellow (3).

## Histogram settings

You can change the number of bins used to plot the histograms with the help of this slider.
