How can you properly negate in the filter engine?

There are two variants:

You can negate the container by selecting "which do not contain". The predicate filter setting must then be set to "equal".

Example: Negating a container

It is also possible to change the predicate of the filter setting to "not equal". The setting of the container has to be set to "which contain".

Example: Negating a filter

The result is the same for both filter variants.

Negating the container is not possible in Auto-Scope.

For more detailed use cases, please read the corresponding training chapter Segmentation and Filter Options at "Negating Containers and Filters".
