In molecular modeling, precise control over structural components is critical. Whether you're docking molecules to predict interactions or visualizing spatial transformations, achieving clarity in these processes plays a major role in obtaining meaningful results. One common challenge for molecular modelers is efficiently undocking molecular groups or meshes to better analyze specific configurations or outcomes. This is where SAMSON's Undock animation comes into play.
Why is Undocking Important?
Undocking isn't just about moving groups of atoms or meshes away from their locations. It's about clarity and precision. For example, undocking can help you:
- Visualize and analyze docked ligand conformations in comparison to undocked states.
- Create cleaner presentations by moving components to clearly showcase docking/interaction details.
- Explore the energy dynamics of multiple atom groups as they transition from interaction sites.
The Undock function in SAMSON automates this process by defining an animation that calculates the optimal final positions of selected nodes away from their docked configurations. This streamlines an otherwise cumbersome task and frees you to focus on your research or presentations.
How to Use the Undock Animation
Implementing the Undock animation in SAMSON is straightforward:
- Select your structural nodes or meshes: In SAMSON, choose at least two nodes. The first node will act as the static receptor, while the rest are the components to be animated away from the receptor. If you want to use multiple receptor nodes, you can group them into a folder and select it as the first node.
- Activate the animation: Double-click the Undock effect in the Animation panel. This action automatically computes the movement amplitude and generates undocked configurations of your selected nodes between keyframes. The animation's keyframes can be adjusted as needed, depending on your desired visual output.
Customization Options
SAMSON gives you additional controls to fine-tune your animation. For example:
- You can adjust the amplitude of the undocking movement using the Inspector tool.
- Modify the smoothness of the transitions between keyframes with SAMSON's Easing curve, which controls how parameters are interpolated over time.
No two molecular configurations are the same, so these options ensure you can tailor animations to meet your specific modeling needs.

Below is an example illustrating the Undock animation:
In the gif above, molecular groups or meshes are smoothly undocked to their automatically computed positions, making it easier to analyze and visualize data. Note that the Animation menu used in this example has since been replaced by the Animation panel in SAMSON's Animator, offering a simpler way to access these features.
Conclusion
The Undock animation is a valuable asset for molecular modelers looking to save time and improve the clarity of their visualizations. By automating this process, SAMSON enhances your ability to focus on scientific insights rather than manual adjustments.
