# Settings

Use the Settings tab to configure the tool to generate a standard deviation image, view the number of images used to create the current average image, and reset the average image to a blank image.

The tab offers the following options:

Option | Description
--- | ---
Standard Deviation Enabled | Determine whether or not the tool calculates the standard deviation image in addition to the average image. Changing the value of this property will clear the current average image.
Number of Images | The current number of images that have been used to calculate the average image.
Reset | Clear the current average image and standard deviation image, if requested.
