For molecular modelers, presenting dynamic changes in molecular structures often requires precision and attention to detail. Whether you are creating a presentation or designing simulations to track atomic movements, keeping a reliable record of atom trajectories plays a crucial role in ensuring clarity and reproducibility. SAMSON offers a solution: the Record path animation.
What is the Record Path Animation?
The Record path animation in SAMSON is a tool dedicated to recording the trajectories of atoms during a presentation. This feature adds a track that captures the movements of selected atoms as they are influenced by other animations, such as Assemble, Dock, or Simulate. The result is a visually rich and scientifically precise path that you can use to enhance your molecular story.
How to Add and Utilize the Animation
Adding the Record path animation is straightforward. Double-click it in the Animation panel of the Animator, which automatically places a keyframe at the current frame. If needed, you can easily reposition the keyframe for better synchronization with your other animations.
The path’s track colors provide helpful visual feedback:
- Green segments: Positions have been successfully recorded.
- Red segments: No positions have been recorded, or the recording has become invalid.

Expert Tips for Optimizing Animations
Creating professional molecular animations requires attention to detail and efficient workflows. Here are two tips to streamline your process:
Tip
The Animator executes animations from top to bottom. Ensure the Record path animation is after any animations that modify atomic positions; otherwise, you risk recording incomplete or inaccurate trajectories.
Tip
You can enable or disable path recording for performance reasons. For instance, disable recording during presentation setup or after you’ve finalized the path. Use the Inspector or right-click the animation in the Animator to toggle Enable recording. When disabled, animation controllers darken as a reminder.
Exporting the Recorded Path
Once your path is fully recorded (represented by a completely green track), you may want to save it as part of your project or presentation. SAMSON makes exporting simple:
- Use the Inspector, and select Create path.
- Alternatively, in the Animator, right-click the Record path animation and select Create path.
This integration allows you to efficiently save, adjust, and present molecular trajectories in a professional and scientifically accurate manner.

Conclusion
Recording atom pathways during molecular simulations is critical for presentations, analysis, and overall clarity. The Record path animation in SAMSON not only simplifies this process but also allows for versatility and customizability.
