In the world of molecular modeling, efficiently manipulating and visualizing molecular structures is a critical yet often complicated task. For many researchers, repositioning atoms or meshes requires tedious manual adjustments that can detract from the focus of their work. But what if there was a way to automate and streamline this process without compromising precision?
The Undock animation in SAMSON provides such a solution. This powerful feature automatically undocks groups of atoms or meshes from their initial, docked positions, moving them to optimized, calculated final positions. Below, we’ll explore how this animation works, its practical applications, and how you can integrate it into your workflow to save time and enhance accuracy.
Why Use the Undock Animation?
The value of the Undock animation lies in its automation, particularly for multi-atom or mesh systems. Instead of manually repositioning elements in a molecular structure and risking inconsistencies, the Undock animation computes the final positions for you. This is particularly useful when:
- Preparing molecular systems for docking studies.
- Creating visual presentations to highlight specific structural details.
- Testing and validating spatial arrangements of docked molecules or mesh-based components.
By handling this task programmatically, the Undock animation reduces repetitive work and ensures reliable, reproducible results every time.
How to Apply the Undock Animation
Getting started with the Undock animation in SAMSON is straightforward:
- Select the elements to be undocked: Begin by selecting at least two structural nodes or meshes in your SAMSON document. Here, the first selected node will act as the static receptor, and the others will be animated. To group multiple nodes as a receptor, create a folder, move these nodes into it, and select the folder as the first node.
- Apply the animation: Open the Animation panel in the Animator and double-click on the Undock animation effect. If no nodes are selected, SAMSON will automatically try to guess the nodes to be undocked.
- Refine your animation: Move the keyframes as needed in the timeline to control the duration and transitions. The amplitude of the motion is calculated automatically but can be modified through the Inspector.
Customization Options
SAMSON allows users to tailor the behavior of the Undock animation to suit specific needs:
- Amplitude: Through the Inspector, you can adjust the movement’s amplitude to align with your desired level of spatial separation.
- Interpolation: By editing the Easing curve, you can define how smoothly the animation transitions between keyframes, offering full control over the perception of motion.
Visual Example
Below is an example of the Undock animation in action:

This example demonstrates how atoms or meshes smoothly move apart to reveal their undocked positions, clarifying spatial configurations in a molecular system.
Streamline Your Workflow
By automating the repositioning of molecular components, the Undock animation helps researchers and molecular designers focus on higher-level tasks. Whether you’re preparing visuals for a presentation, setting up simulations, or simply exploring structural arrangements, this feature can make intricate workflows remarkably straightforward.
