For molecular modelers, analyzing trajectories or cycling through conformations is a frequent task, yet ensuring an intuitive and smooth workflow can be challenging. The Play path animation in SAMSON makes this process remarkably straightforward, providing an efficient way to visualize molecular paths.
The Play path animation allows you to animate simply by selecting a path or multiple paths between two frames. This is especially useful for anyone working on molecular simulations, conformational analysis, or any scenario that relies on inspecting trajectories. Want to see how a molecule moves across states or explore a trajectory over time? This animation tool makes such inspections easy.
How Does It Work?
Here’s how you can start using the Play path animation step-by-step:
- Select a Path: Identify the path you want to animate in SAMSON’s user interface.
- Add the Animation: Open the Animation panel of the Animator and double-click the Play path animation effect. This will link the animation to the selected path.
- Adjust Keyframes: By default, the animation spans the entire path between the two keyframes. Keyframes, which mark specific points in your animation timeline, can be moved to fine-tune how and when the path is played.
The ease of use combined with the flexibility to adjust timings ensures this animation tool fits naturally into molecular modeling workflows. Furthermore, if you have multiple paths selected, the animation will synchronize them, enabling a simultaneous playback experience.
Smoothing vs. Frame Matching
If the number of frames in the animation doesn’t match those in the path, SAMSON automatically applies a smoothing function to ensure fluid motion. However, if precise frame-to-frame analysis is your goal, you can disable smoothing via the Inspector. This level of control over the animation’s parameters makes the Play path tool adaptable to varied uses, from quick overviews to detailed inspections of molecular trajectories.
Expanding Your Capabilities with Easing Curves
Customizing the feel of your animations is another important aspect. Using the Easing curve, you can control how the animation’s parameters interpolate between frames. Whether you’re after smooth acceleration, linear transitions, or custom dynamics, easing curves offer the versatility to match your needs.

Why Choose Play Path Animation?
In a field where precision often meets complexity, tools that simplify workflows are invaluable. The Play path animation not only simplifies streamlining the visualization of molecular motion, but also enhances interpretability. This becomes particularly beneficial for tasks like:
- Examining simulation trajectories.
- Analyzing transition states.
- Creating high-quality presentations or animations for communication.
With a few adjustments and clicks, you can transform raw trajectory data into comprehensible animated visualizations.
