As molecular modelers, we often face the challenge of effectively presenting complex molecular simulations to different audiences. A common pain point is maintaining attention on critical moments in a visual presentation—whether it’s to explain a mechanism, emphasize a key interaction, or allow an audience to absorb complex molecular behavior. This is where the Pause animation feature in SAMSON comes to the rescue.
The Pause animation in SAMSON allows you to temporarily pause your presentation at a specific frame, giving your viewers time to grasp the important details. This is particularly helpful when presenting time-critical animations or illustrating dynamic simulations where certain points need extra focus. Here’s how you can integrate this feature efficiently into your workflow:
Adding the Pause Animation
In SAMSON, adding the Pause animation is straightforward. Navigate to the Animation panel within the Animator. Double-click on the Pause animation effect, and a keyframe for the pause will be placed at the current frame.
If you need to adjust the timing, you can freely move the keyframe to ensure the pause occurs exactly when needed. For example, you might want to highlight a ligand binding event or freeze the scene while explaining a structural alignment.
Note:
You can always reposition the pause keyframes to refine your presentation flow.
Customizing the Pause Duration
The duration of the pause can be personalized to suit different scenarios. To specify how long the pause should last, select the animation node in the Document view, then adjust its properties in the Inspector.
This flexibility allows you to synchronize the pause duration with your narrative—whether it’s a short pause to highlight a quick transition or a longer one for analyzing a complex event. The Pause animation ensures you stay in full control of the pace of your presentation.

Practical Applications
Here are a few examples of how you can use the Pause animation in your molecular modeling workflows:
- Highlighting Key Frames: Stop at a frame showing a molecular interaction that requires explanation.
- Teaching and Outreach: Pause at milestones during presentations or lectures to engage your audience.
- Analysis in Teams: Use pauses to ensure collaborators can collectively examine specific snapshots of a simulation.
By using the Pause animation, your presentations can become more focused, engaging, and effective in delivering scientific insights.
