Docking and undocking atoms or groups is a fundamental operation in molecular modeling, enabling researchers to explore structural configurations and refine molecular interactions. But how can you efficiently undock groups of atoms or meshes from their docked positions while maintaining precision in your workflows?
The Undock animation in SAMSON simplifies this task by automatically computing final positions away from the docked configurations. This feature is particularly useful for simulating molecular dissociation, positioning components for further analysis, or even preparing presentations to communicate complex concepts.
Applying the Undock Animation
To use the Undock animation, follow these steps:
- Select at least two structural nodes or meshes in the document. One of these nodes will act as the static receptor, and the others will be animated. If you want multiple nodes to function as the receptor, organize them into a folder and select that folder as your receptor node.
- If you skip the selection step, SAMSON will attempt to guess which nodes the animation should be applied to.
- Activate the Undock effect by navigating to the Animation panel of the Animator and double-clicking on the Undock effect.
The selected nodes will undock between two keyframes. You can then adjust the keyframe timings and positions as needed.
Customizing the Effect
If you need to fine-tune the amplitude of movement, simply inspect the animation. Using the Inspector, you can modify this amplitude to refine how far the nodes move during the undocking process.
Additionally, you can configure how parameters are interpolated between frames by adjusting the Easing curve. This level of control ensures your animation results align exactly with your experimental or presentation goals.
Why Use Undock?
Undocking manually or without guided computation can quickly introduce inaccuracies, especially when positional relationships among nodes are critical. With SAMSON’s Undock animation, you save both time and effort by automating the process effectively. Furthermore, the precise control over properties and interpolation allows you to create smooth and intuitive animations for analysis and presentations.

Conclusion
The Undock animation is a helpful tool for molecular modelers who need to explore docked interactions, simulate dissociation events, or create impactful visual presentations. With intuitive tools like the Inspector and Animator, you can customize animations with ease.
