When creating molecular presentations, one common challenge scientists face is how to focus the audience’s attention on specific areas of a structure. Highlighting key regions, while minimizing distracting elements, can make all the difference during a presentation or tutorial. This is where the Conceal Atoms animation feature in SAMSON can help. By making atoms and the bonds between them progressively vanish, you can emphasize critical molecular substructures with clarity and precision.
How the Conceal Atoms Animation Works
The Conceal Atoms animation hides atoms and bonds progressively between frames, allowing for a clean and detailed transition. Notably, it manages visibility through node states rather than adjusting transparency. This subtle distinction ensures that concealed elements truly disappear, creating uncluttered visuals.
The animation comprises four keyframes:
- Between keyframes 1 and 2: All targeted atoms and bonds are fully visible.
- Between keyframes 2 and 3: Atoms and bonds progressively disappear, based on their sequence in the selection.
- Between keyframes 3 and 4: All targeted atoms and bonds are fully hidden, leaving only the desired portion of the structure visible.
You can move and adjust the keyframes as per your presentation needs, enabling flexibility in timing and storytelling.
Adding the Conceal Atoms Animation
Here’s how to apply the Conceal Atoms effect to your molecular model in SAMSON:
- Select the atoms and bonds you want to progressively disappear.
- Open the Animation panel within the Animator module of SAMSON.
- Double-click on the Conceal Atoms effect to add it to your animation.
Once applied, you can modify the easing curve to control how the concealment behaves between keyframes, ensuring smooth and natural transitions.
Illustrative Examples
The Conceal Atoms animation is ideal for presentations that involve zooming in on binding pockets, comparing conformational states, or focusing on critical residues in protein structures. For instance:
- The 1AF6 – Fly around presentation uses such animations to elegantly navigate through molecular structures.
- Similarly, in 1AF6 – Fly around – 2, concealment helps focus on important regions, guiding viewers seamlessly.

Incorporating these techniques doesn’t just make presentations visually appealing, but also enhances audience engagement by keeping the focus exactly where it needs to be.
