One of the challenges in molecular modeling lies in effectively visualizing and analyzing the complex trajectories generated during simulations. Whether you’re cycling through conformations or revisiting molecular dynamics paths, the ability to reverse those pathways can provide useful insights. SAMSON's Play reverse path animation is here to address this need.
What is the Play Reverse Path Animation?
The Play reverse path animation allows you to play a single or multiple paths between two frames—completely in reverse. Paths in SAMSON are used to store trajectories, making this feature an intuitive tool for reviewing motions or simulating reverse processes.
Suppose you’ve simulated a protein unfolding event. With this animation, you can visualize the unfolding process in reverse, effectively 're-folding' your protein for enhanced understanding. Similarly, molecular docking paths or conformational cycles can be replayed backward to highlight key structural transitions.
Why Reversing Paths Matters in Molecular Visualization
In molecular modeling, reverse animations can help answer questions such as:
- What were the intermediate conformations during a structural change?
- How do specific molecular interactions evolve when reversed?
- Can smoother interpolations emphasize important aspects of your simulation?
By combining animations with SAMSON’s features like synchronized path playback and adjustable animation frames, this tool provides a highly customizable visualization approach.
How to Add and Customize the Animation
Here’s a step-by-step guide to get started with Play reverse path:
- Select a path node containing the trajectory you wish to reverse.
- Open the Animation panel within the Animator section of your SAMSON interface.
- Double-click on the Play reverse path animation effect to add it to your scene.
- Adjust keyframes in the Animator to refine playback timing.
Note: This tool also allows path smoothing. However, you can disable smoothing within the Inspector panel if equal frame counts across your animation and path are unnecessary.
Fine-Tuning Interpolation with Easing Curves
As trajectories may require additional emphasis at certain intervals, SAMSON lets you customize interpolation parameters using Easing curves. These options ensure flexibility, so your animations align perfectly with the analytical story you seek to convey.
An Example of Reverse Path Animation in Action
Imagine you have a protein that cycles between two functional states. By applying Play reverse path, you can not only study its forward transitions but also highlight reverse movements. Pair this with synchronized multiple paths for comparative visualization across different trajectories. Below is an example image of the tool in action:

The Play reverse path animation is just one of the many ways SAMSON simplifies complex molecular trajectories. Visualize movements, highlight reverse processes, and customize paths to showcase molecular interactions more effectively.
