Molecular modeling often involves simulating interactions between structures, like proteins and ligands, or analyzing docking poses of molecules. A key challenge for modelers is efficiently and accurately positioning groups of atoms or meshes into docked configurations, especially when creating animations or presentations for their work. SAMSON’s Dock animation provides a straightforward solution to this challenge, allowing users to create visual presentations that dynamically showcase docking processes.
What is the Dock Animation in SAMSON?
The Dock animation in SAMSON is designed to help users dock structural groups such as atoms or meshes to specific positions, known as “docked positions.” It automatically calculates starting positions away from these docked positions and smoothly animates the transition between the two states. This feature is ideal for illustrating molecule docking, guiding viewers through conformational changes, or simply presenting your molecular design process.
How to Use the Dock Animation
Getting started with the Dock animation is straightforward:
- Select Your Structures: In your SAMSON document, select at least two structural nodes or meshes. The first selected node acts as the static receptor, while the others are animated. If you want multiple receptor nodes, group them into a folder and select the folder as the first node. If no selection is made, SAMSON attempts to determine the appropriate nodes for animation.
- Add the Animation: Open the Animation panel in the Animator, and double-click the Dock animation effect.
- Adjust Keyframes: The animation operates between two keyframes. You can move these keyframes on the timeline as needed to control the timing of the docking movement.
By default, SAMSON calculates the amplitude of movement automatically when the animation is created. If you want to modify this property, use the Inspector tool to adjust the amplitude and make refinements to the animation.
Refining Your Animation
You can customize how the animation progresses between frames by modifying the easing curve. This gives you control over the interpolation of parameters between frames, enabling smoother and more realistic movements.
Note
You can always adjust the positions of the keyframes and tweak the animation as your project evolves!

Why Use Dock Animation?
The Dock animation is a powerful tool for creating compelling molecular presentations or exploring docking scenarios with ease. By harnessing this feature, molecular modelers can improve their visualizations and make them more accessible to broader audiences, such as researchers, students, or collaborators.
