Molecular modelers often face the challenge of repositioning selected atoms or groups detached from a fixed receptor for visualization or analysis purposes. Tasks like observing ligand dissociation or undocking protein subunits can be tedious, especially without an efficient workflow or automation tool. This is where SAMSON’s Undock animation brings a streamlined solution to life.
The Undock animation in SAMSON simplifies the process by automatically computing the new positions of undocked atoms or meshes, ensuring they move naturally away from their currently docked positions. This animation is particularly helpful for researchers and educators looking to present molecular dissociation events vividly in their projects or instructional materials.
How to Add and Use the Undock Animation
Getting started with the Undock animation is straightforward. Follow the steps below:
- Select the nodes or meshes: To apply the Undock animation, ensure you have at least two structural nodes or meshes selected in your document. Typically, the first node will act as the static receptor, while the others will move. If multiple nodes should comprise the receptor, you can organize them into a folder and select the folder as the first node. If no specific selection is made, SAMSON will make an educated guess about the applicable nodes in your document.
- Activate the animation: Access the Animation panel within the Animator (available via Interface > Animator) and double-click on the Undock animation to apply it. This action will automatically insert two animation keyframes, between which the undocking movement occurs.
- Refine adjustments: The amplitude of the undocking motion is computed automatically upon animation creation. For further precision, adjust the movement’s amplitude or refine parameter interpolation between the frames by using the Easing curve.
Keyframes can be moved in the Animation timeline for finer control. Adjust their positions to fit the pacing and emphasis of your presentation as needed. Remember, an intuitive inspector interface is available to help you tweak these parameters seamlessly!
One Important Tip
The SAMSON documentation highlights an optional approach to manage receptor nodes. Creating a folder for multiple receptor components saves time and ensures every relevant node acts as the receptor during the animation process. Incorporating good organization practices when creating animations like Undock adds efficiency to any molecular modeling workflows.

Conclusion
The Undock animation is a valuable tool that simplifies the molecular modeling workflow, providing both learners and professionals with a user-friendly way to explore or showcase undocking processes. By removing manual calculations and offering automatic, intuitive controls, it enhances not only productivity but also the overall modeling experience.
