In ZEN Connect you can use a mode called Global-Z if you have a project with at least one z-stack. In this mode, you can change the displayed z plane of all z-stacks in the project with only one slider, the Global-Z slider. The range of the slider is comprised of the z values of all stacks in the project. The displayed slice for each stack is always the one closest to the value set by the Global-Z slider, as long as the value is within the boundaries of the entire stack. When you use the Global-Z slider and are beyond the range of a certain z-stack, only a frame is displayed to show where the stack is positioned.
Note: If you have selected a particular z-stack, the Global-Z and Z-Position sliders are interdependent. Changing the value with one slider updates the other slider as well.

1. You have one or several z-stacks in the ZEN Connect project.

1. Activate the Global-Z checkbox on the Dimensions tab.
2. Use the slider or the input field to set a global value for z.

1. All the slices closest to the set value are displayed for all z-stacks. Z-stacks which are out of range are illustrated by an empty frame.
