Molecular modelers often face a recurring challenge: how to efficiently manipulate complex structures and visually present key interactions or changes in molecular conformations. One common task is undocking groups of atoms or meshes from their docked positions. With SAMSON's Undock animation, you can simplify this process and produce clear, intuitive visualizations.
Why Use the Undock Animation?
The Undock animation helps reposition groups of atoms or meshes that are considered docked at certain positions. The system automatically computes final positions that move these objects away from the docked states, providing clarity in multi-structure systems.
This capability is particularly beneficial for presentations, animations, or analyses of docking processes, where showing the undocking step is integral to understanding molecular interactions.
How to Easily Implement an Undock Animation
Here's how to add and customize an Undock animation step-by-step:
-
Select your nodes or meshes: Start by selecting at least two structural nodes or meshes within your SAMSON document. The first node acts as a static receptor, while the others will be animated. If several nodes serve as the receptor, move them to a folder and select the folder as the first node. When no selection is made, SAMSON makes its best guess for node assignment.
-
Add the Undock animation: Open the Animation panel within the Animator interface and double-click on the Undock effect. The between-keyframe animation will automatically apply to selected nodes.
-
Adjust keyframes: Customize the undocking process by moving the corresponding keyframes of the animation timeline to fine-tune the timing.
-
Modify animation amplitude: By default, SAMSON computes amplitude for undocking. If needed, use the Inspector to manually adjust this parameter.
Advanced Customization: Interpolation Options
For even finer control, you can define how animation parameters interpolate between keyframes. This is done by modifying the Easing curve, which lets you adjust the rate of change over time. For example, you can make transitions appear more natural or emphasize particular moments in the undocking process.

Applications and Productivity Boosts
Whether you are visualizing molecular conformational shifts, explaining drug docking and undocking mechanisms, or analyzing rigid body transformations, the undock animation can help you efficiently focus on what matters most: clear and comprehensive data presentation.
For inspiration, consider this 2AZ8 Dock animation or this 5SAT Dock animation, which effectively demonstrate the concepts.
