For molecular modelers and researchers, capturing and analyzing molecular trajectories can often be a challenge, especially when crafting complex animations or presentations. The Record path feature in SAMSON offers a powerful, efficient tool to document atom trajectories during animations, ensuring that your work is both visually enlightening and scientifically precise.
What is Path Recording?
Path recording in SAMSON involves creating a track that preserves the trajectory of atoms during an animation. Whether you’re simulating molecular docking, assembling components, or moving atoms manually, Record path enables you to document these movements, step by step. This feature is invaluable for gaining insights into atomic dynamics and sharing these trajectories effectively during presentations.

How to Add the Record Path Animation
Adding the Record path animation to your project in SAMSON is simple. Follow these steps to get started:
- Open the Animator and navigate to the Animation panel.
- Double-click on the Record path animation effect. This will place a keyframe at the current frame in your presentation.
- Drag and move the keyframe if needed to precisely align it with other animation effects.
The tracks created by the Record path animation are color-coded to guide you:
- Green segments: Positions have been successfully recorded.
- Red segments: Positions have not yet been recorded or have become invalid.
Optimizing Your Workflow with Helpful Tips
To achieve the best results, keep in mind the following tips:
- The Animator executes animations in top-down order. Ensure the Record path animation is positioned after the ones you wish to record.
- Once the path has been fully recorded, consider disabling path recording to enhance performance while refining your presentation.
- You can toggle recording on or off using the Inspector or by right-clicking the animation in the Animator.
Exporting and Sharing the Path
Once you’ve fully recorded your path (indicated by a fully green animation), you can convert it into a Path node within your document. Here’s how:
- In the Inspector, click Create path.
- Alternatively, right-click on the Record path animation in the Animator and choose Create path.
This method preserves the trajectory data you need, making it simple to analyze or share your findings with colleagues.

Why Use Path Recording?
Molecular modelers often spend significant time ensuring that their animations accurately reflect atomic movements. The Record path feature eliminates guesswork and ensures you have a reliable record of all positional changes. This capability allows for better interpretation, communication, and collaboration in molecular design projects.
