One of the common challenges in molecular modeling is managing the dynamic positioning of groups of atoms or meshes, especially when transitioning from docked configurations. Whether you’re adjusting a molecular presentation or preparing a model for analysis, controlling the undocking process can save time and improve accuracy. In this post, we will explore how to apply the Undock animation in SAMSON to smoothly undock groups of atoms or meshes with precision.
What Is the Undock Animation?
The Undock animation in SAMSON is designed to displace groups of nodes, such as atoms or meshes, from their docked positions to new, automatically computed positions farther away from these original locations. This allows for clean transitions in molecular animations or presentations. The entire process is seamlessly computed, saving you the effort of manually repositioning each component.
Additionally, the undocking effect integrates effectively with other animations available in SAMSON, such as Dock or Move atoms.
Step-by-Step: How to Apply the Undock Animation
Here’s how you can implement the Undock animation in SAMSON. These steps will guide you through the process:
- Select your nodes: Use the Select tool to choose at least two structural nodes or meshes. The first node represents the static receptor (stationary point), while the other chosen nodes will be animated. If you have multiple receptor nodes, group them in a single folder and select the folder as the first node.
- Access the Animation panel: Open the Animator and double-click on the Undock animation effect within the Animation panel.
- Position your keyframes: The undocking animation acts between two keyframes. Adjust their positions on the timeline to define when the undocking occurs and its duration.
Customizing the Animation
SAMSON calculates the amplitude of the undocking movement automatically during the creation of the animation. However, this setting can be customized. To modify the amplitude or other properties of the animation, inspect it using the Inspector tool.
You can also refine how the animation transitions between frames by editing its Easing curve. The Easing curve allows smooth interpolation of animation parameters, enhancing the professional quality of your molecular presentations.

When to Apply the Undock Animation
The Undock animation is especially useful for demonstrations, educational purposes, and presentations. It effectively communicates structural transformations or relationships between molecular components. Additionally, it can be invaluable when dissecting docked configurations and exploring spatial relationships in molecular models.
Conclusion
The Undock animation in SAMSON provides a practical solution for undocking molecular components. Its ease of use, combined with customizable parameters, makes it an essential tool for molecular modellers seeking smooth and professional animations.
