For molecular modelers, animating complex molecular interactions is often time-consuming and technically challenging. In particular, creating a seamless undocking process for atoms or molecular meshes can feel tedious, especially when precision and presentation clarity matter the most. That’s where SAMSON’s Undock animation effect comes in—a straightforward solution to animate molecular components separating from their docked positions.
What is the Undock animation?
The Undock animation in SAMSON allows structural nodes (e.g., groups of atoms or meshes) to “undock” from their starting positions, which are considered docked positions. The animation automatically computes the final positions of these components, ensuring they move away from the original docked state. This automation saves valuable time when showcasing changes in molecular systems, such as ligand-receptor interactions or protein unfolding events.
How to set up the Undock animation
Adding the Undock animation to your scene is straightforward, even for beginners:
- Select nodes: Identify the elements to undock by selecting at least two structural nodes or meshes in the document.
- Define roles: The first node is treated as the static receptor, while the rest are animated. If multiple nodes should act as a single receptor, place them in a folder and select this folder as the first node in your selection. If no nodes are selected, SAMSON will attempt to intelligently guess which nodes to undock.
- Activate the animation: Open the Animation panel in the Animator, and double-click on the Undock animation effect to apply it.
You’ll see the selected nodes undock over the span of two keyframes. Adjust the timeline as needed by modifying the positions of these keyframes to fine-tune timing.
Fine-tuning the movement
By default, the movement amplitude is calculated automatically, ensuring that the undocked nodes are properly separated. However, SAMSON provides flexibility for advanced users:
- You can inspect the animation and manually adjust the amplitude to achieve the desired visual separation.
- Use the Easing curve to control how parameters are interpolated between frames, creating smooth or dynamic transitions based on your needs.
Why the Undock animation is worth exploring
Imagine you’re demonstrating a protein-ligand docking simulation to a colleague or during a presentation. Without an animated representation, explaining such a process can become abstract or difficult to follow visually. The Undock feature minimizes ambiguity by automatically generating clear separations, helping viewers grasp key molecular changes at a glance.
This effect is not only useful for scientific presentations but also enables modelers to validate molecular behavior dynamically over time. Its automation reduces manual workload, making SAMSON a valuable tool for any researcher or educator in molecular science.
