Maintenance Trees Clean

Maintenance - Clean descriptor trees

To administer the recommended modifier values select the Maintain descriptor trees tab and choose the tab Clean decriptor trees. Select the Project, the Descriptor tree and the Entity type (“Statistical measure”, “Modifier” or “Frequency”) that shall be cleaned. Currently three cleaning options are supported:

• Unsuitable recommended values - Clear recommended values the do not match the descriptor type, e.g. statistical measures for a categorical descriptor.
• Recommended values for tree nodes - Clear recommended values that are not directly assigned to a descriptor, but a tree node. You should only perform this operation if you are sure that the neccessary values have been directly assigned to the approriate descriptors.  
• All values in the descriptor tree - Delete all recommended values. Only descriptor trees can be selected for this option, that are not marked as “complete”. You should only perform this operation if you are sure that the neccessary values have been assigned to a complete descriptor tree of the project.
