A Step-By-Step Guide to Recording Atomic Trajectories with SAMSON

One of the common challenges in molecular modeling is tracking the movement of atoms during simulations or animations. Whether you are analyzing molecular docking results, studying complex assemblies, or simulating dynamic molecular interactions, being able to visualize and save atomic trajectories can provide invaluable insights. Thankfully, the Record path animation in SAMSON makes this process straightforward and highly visual.

Why Use the Record Path Animation?

The Record path animation in SAMSON allows you to capture atom trajectories over the course of a molecular presentation. Instead of wondering about the movement of atoms during a dynamic simulation or manually attempting to piece trajectories together, this feature visually records the path and stores it for deeper analysis. You can combine it with animations like Assemble, Dock, or Simulate to track outcomes dynamically.

Adding and Working with the Record Path Animation

To start recording trajectories, simply double-click the Record path effect in the Animation panel within SAMSON’s Animator. By default, the keyframe for the animation will appear at the current frame. You can drag and reposition the keyframe as needed if you want the recording to begin at a different point during your presentation.

SAMSON visualizes the recording status using color indicators:

  • Green segments: Positions have been successfully recorded at that frame.
  • Red segments: Positions are either not yet recorded or invalid.

Here’s what it looks like during progress:

Practical Tips to Enhance Efficiency

Here are some practical insights to help you get the most out of this feature:

  • Order of Execution: Animations in SAMSON execute top-down. Make sure to place the Record path animation below any animations you want to track.
  • Performance Considerations: If you’re still tweaking your presentation or once you’ve fully recorded a path, you can disable recording to optimize performance. You can do this in the Inspector or by right-clicking the animation in the Animator and toggling Enable recording. Disabled recordings will appear darkened in the interface.
  • Keyframe Adjustments: Feel free to move the keyframes to refine where the recording starts or stops.

Exporting Recorded Paths

When the path is fully recorded (indicated by the animation being completely green), you can export the trajectory as a node in your document. There are two ways to do this:

  • In the Inspector, click the Create path button.
  • Right-click on the Record path animation in the Animator and select Create path.

Here’s how the interface looks while creating a recorded path:

Conclusion

The Record path animation is an essential feature for molecular modelers who need a clear visualization of atomic trajectories. With its intuitive interface and compatibility with other animations, it streamlines atomic motion analysis and enhances data collection.
