Molecular modelers often grapple with the challenge of efficiently visualizing complex molecular systems. Whether it’s protein-ligand interactions, detailed structural analysis, or preparing impactful presentations, configuring the perfect visualization can be daunting—colors, representations, node selections, and more need careful setup. Enter Visual Presets in SAMSON, a feature designed to simplify and accelerate your molecular visualization workflow while offering customization potential tailored to your needs.
The Power of Visual Presets
Visual presets are essentially predefined schemes that combine multiple visual representations, color schemes, and actions for molecular systems. A single click can instantly transform your visualization, showcasing your molecular structure exactly as desired without manually setting every parameter.
SAMSON provides a variety of default visual presets, but where it truly excels is in enabling you to create, edit, and save your own presets. This means you can standardize your styles for specific workflows or presentations, ensuring consistent and effective visual communication.
How to Create Your Own Visual Presets
Creating a customized visual preset is straightforward. Here’s how you can craft one that suits your specific requirements:
1. Start from Scratch or an Existing Preset
You can access preset customization via the Home or Visualization menu. Choose “Create…” to build a new preset from scratch. Alternatively, select an existing preset and modify it.
If starting fresh, click the 
button to add a new step to your preset.
2. Define Steps and Selections
Each preset can comprise multiple steps. For each step:
- Choose a selection of nodes to work with. For example, “Receptor”, “Ligands”, or “Any node”. If needed, you can create custom selections using the Find window powered by SAMSON’s Node Specification Language.
- Add actions like hiding specific atoms, labeling atoms, or zooming to a defined selection. Actions layer sequentially within a step.
- Apply a visual model such as Van der Waals surfaces, ribbons, or licorice representations. This gives clarity to molecular structures.
- Set a color scheme (e.g., per chain, by element, or constant color) for added distinction and emphasis.
3. Customize Colors and Palettes
If a color scheme is defined, SAMSON allows easy palette customization. Double-click the palette field to select or create a custom palette in the pop-up dialog. Constant color schemes can also be edited by double-clicking, enabling fine control over the visual presentation.
4. Organize Steps and Save
You can reorder steps using the Move up or Move down options or delete unnecessary steps. Once your preset is complete, save it for future use. It will be loaded automatically each time you launch SAMSON, allowing you to streamline your projects.
Why Visual Presets Matter
Molecular visualization is not just about aesthetics—it’s about communicating structural insights effectively. With customizable visual presets, you can focus your time and energy on your research rather than repetitive visualization tasks. Whether refining visuals for publication or rapidly exploring new molecular systems, these presets are a game-changer.
