In molecular modeling, achieving precise and reproducible animations can be a key challenge. For many molecular modelers, one recurring question is: how can we ensure certain atoms stay fixed, maintaining their positions across animations? If you’ve been facing this pain point, SAMSON’s Hold atoms animation feature might just have the solution for you.
Why Hold Atoms?
When animating molecular systems, it’s common to encounter scenarios where parts of the system must remain stable for analysis, teaching, or presentation purposes. For instance, while simulating ligand binding or molecular complex formation, ensuring that some atoms or groups retain their original positions can provide visual clarity and aid in conveying the process effectively. The Hold atoms animation feature in SAMSON allows you to anchor a group of selected particles between two frames, ensuring they stay exactly where you want them.
How to Use the Hold Atoms Animation
Here’s a step-by-step guide to using this feature effectively:
- Select the atoms: Navigate to the relevant section of your model and use the selection tools in SAMSON to highlight the group of atoms or particles you wish to keep fixed.
- Add the animation: Open the Animation panel in the Animator. From there, double-click on the Hold atoms animation effect.
- Adjust the keyframes: The selected atoms will now remain fixed between the two keyframes. You can move these keyframes as needed to structure your animation and tailor the timing to your project requirements.
This makes holding atoms intuitive and straightforward, especially for those working on intricate molecular animations.

Important Notes
It’s worth noting that while older versions of SAMSON included an Animation menu, this has now been streamlined. You can access all animations via the Animation panel within the Animator interface, making the process cleaner and quicker. You can also move or modify keyframes at any point based on your evolving animation needs.
