One of the challenges for molecular modelers is to effectively communicate complex motions and transformations of molecules, whether for sharing with colleagues, teaching, or showcasing findings. To address this, SAMSON’s Record path animation provides a way to seamlessly capture the motion of atoms across presentations as a path, enabling insightful and visually compelling outputs.
The Core Idea: Recording Paths
The Record path animation tracks and captures atomic trajectories as paths during a presentation. This feature is invaluable when working with animations such as Assemble, Move atoms, or Simulate to document molecular motions. By recording these transformations, you can create clear and repeatable content that highlights critical movements in molecular designs.
How to Add the Record path Animation
Integrating this animation into your molecular presentation is straightforward:
- Navigate to the Animation panel within the Animator.
- Double-click on the Record path option to add it to your timeline. You can reposition the keyframe at your desired frame.
Once added, pay attention to the segment colors of the path track:
- A green segment indicates positions have been successfully recorded.
- A red segment indicates positions haven’t been recorded yet or have become invalid.

Pro Tips for Efficient Recording
Here are some tips to optimize your recording process:
- Ensure the Record path animation is positioned after animations affecting atomic positions (e.g., translations or rotations). Since the Animator operates top-down, the order of animations on the timeline is significant.
- You can adjust the animation’s keyframes if needed for tighter control over when recording starts or ends. This enables greater customization of presentation flow.
- For performance optimization, disable path recording when it isn’t needed. Right-click the animation in the Animator or use the Inspector and toggle Enable recording. Darkened controllers help indicate that recording is off.

Exporting Your Path
Once your animation is fully recorded (green segments throughout), exporting the path is simple:
- Use the Inspector to select Create path for this animation.
- Alternatively, right-click on the Record path animation in the Animator and choose Create path.
This generates a Path node in your document, which can be further utilized to build comprehensive molecular presentations or for record-keeping of molecular movements.
Take Advantage of Robust Animation Tools
Capturing atomic trajectories with paths not only enhances the clarity of molecular presentations but also allows for streamlined sharing of reproducible molecular motions. Whether you’re showcasing how a molecule docks, simulating dynamic transitions, or observing atom relocations, the Record path animation in SAMSON lets you preserve these details effortlessly.
