If you’ve ever encountered the challenge of disentangling or separating molecular groups in your structural models, you know this task can be cumbersome. The Undock animation in SAMSON provides a clean and efficient way to address this issue, making it much easier to undock groups of atoms or meshes from their original positions in your molecular designs.
What Is the Undock Animation?
The Undock animation works by freeing molecular groups or meshes from their current docked positions. SAMSON automatically computes the final undocked positions at a distance from the initial docked ones. This animation is particularly useful for molecular modelers who need to demonstrate structural flexibility, simulate molecular dynamics, or create educational visualizations of molecular systems in motion.
For example, you might use the Undock animation to visualize ligand unbinding from receptors, unfolding protein structures, or separating complex molecular assemblies. The result is both visually coherent and customizable to meet your specific scientific or educational goals.
Step-by-Step: Applying the Undock Animation in SAMSON
Here’s how you can seamlessly integrate the Undock animation into your molecular modeling projects:
- Select Your Nodes: Start by selecting at least two structural nodes or meshes in your document. If multiple nodes need to act as static receptors, group them into a folder and select the folder as the primary node. If you skip this step, SAMSON will automatically guess the applicable nodes for the animation.
- Open the Animation Panel: Double-click on the Undock animation effect in the Animation panel within the Animator. This will apply the animation to the selected nodes.
- Adjust Keyframes: The Undock animation will apply between the two keyframes. You can shift the keyframes to control the timing and sequence of the animation as needed.
- Refine Movement Amplitude: Initially, SAMSON computes the movement amplitude automatically. You can further modify this parameter via the Inspector to tailor the results precisely to your needs.
Customization Options
The Undock animation offers customization tools to ensure your results are both accurate and visually impactful:
- Inspector: Use SAMSON’s Inspector to modify the amplitude of the undocking motion. This is particularly useful if you want to highlight or de-emphasize the distance moved by the molecular groups.
- Easing Curve: By adjusting the easing curve, you can control how the undocking movement is interpolated between keyframes. Smooth or dynamic transitions can be achieved depending on your use case.
Practical Use Cases
The following examples illustrate how the Undock animation contributes to molecular modeling projects:
- Simulating the unbinding of a ligand from its binding site in a receptor protein.
- Demonstrating the dissociation of molecular complexes such as dimers or trimers.
- Creating educational visualizations of molecular events for teaching or presentations.

Conclusion
The Undock animation is an essential tool for molecular modelers seeking to demonstrate structural dynamics in an intuitive and visually compelling manner. Whether you’re working on scientific simulations or educational content, this animation streamlines your workflow and enhances your final output.
