Expert Preferences GUI

Expert Preferences GUI How To

The Preferences Expert GUI allows you modify the default preferences for any function. Default preferences are the options used when a call to a function does not otherwise specify a value. These are also the options returned when the function is prompted for its default options. All options have "factory default" values defined by the software. The user may, however, override these defaults using this GUI.

WARNING! The Expert Preferences GUI allows access to low-level options which, if set incorrectly, can cause the program to malfunction or alter program results. The user is encouraged to read the full documentation for any function prior to changing the default preferences. Read the section below on Clearing Existing Default to understand how to return the settings back to their factory default values.

Viewing Current Defaults and Override Values

To modify or view the current default options for a function, enter a function name (e.g., "pca") and check the View Options checkbox. The GUI will show all the current default options settings for the selected function. Note that when the View Options checkbox is checked, you will always see all options for a given function (whether or not the factory default values are currently being overridden with a user-defined default). When View Options is unchecked, you will only see the list of current user-defined overriding defaults, including some system-set overrides.

Setting a Override Value for Defaults

Enter a function name and an option name (or select the function and option from the list) to modify. Enter a new overriding value or edit the current overriding value for the option and click "Set" to make this value the default preference for that option.

Clearing Override Values for Defaults

If you want to clear an existing overridden option, enter the function name and option name (or click on it in the list) and click "Factor Default".
