Why ‘Conceal Atoms’ Is Useful for Molecular Modelers
Visualizing molecular interactions often comes with its own set of challenges. One of the common pains faced by molecular modelers is decluttering complex structures to highlight specific areas of interest. For instance, what if you wanted to focus on a ligand binding site without being distracted by the surrounding atoms? SAMSON’s Conceal Atoms animation allows you to progressively hide selected atoms and bonds, creating cleaner and more focused visualizations.
In this blog post, we will explore how to set up and customize this animation step by step, ensuring you can dynamically simplify structures for presentations or analysis.
How the ‘Conceal Atoms’ Animation Works
The Conceal Atoms animation makes atoms and their associated bonds disappear progressively between two frames. Importantly, this effect is achieved by modifying the visibility of nodes, not their transparency. This ensures hidden elements are entirely removed from view, rather than becoming semi-transparent distractions.
Step-by-Step Guide to Using the Animation
- Choose the Atoms: First, select the atoms and bonds that you want to progressively hide. These might be those unrelated to your focus of interest, such as solvent molecules or sidechains far from the active site.
- Add the Animation: Open the Animation Panel in the SAMSON Animator and double-click the Conceal Atoms effect. This will add the keyframes for your animation right away.
- Understand Keyframes: This animation uses four keyframes to define its behavior:
- Between keyframes 1 and 2: All selected atoms and bonds remain visible.
- Between keyframes 2 and 3: Atoms and bonds progressively disappear based on their order in the selection.
- Between keyframes 3 and 4: All selected atoms and bonds are hidden.
- Adjust Keyframes: You can move the keyframes along the timeline to match the pace of disappearing atoms to your presentation needs.
Customizing the Animation
The Conceal Atoms animation offers flexibility through the Easing Curve. By modifying the easing curve, you gain control over the transition speed between frames. For example, you can make atoms disappear in an exponential, smooth, or linear manner. Experimenting with these curves can help you align the animation with the tone or purpose of your visualization needs.
Practical Example
Imagine highlighting the key structural differences between two conformational states of a protein. By first showing the full molecular structure and then gradually concealing peripheral atoms, you can bring the core differences into focus dynamically.
