One of the frequent challenges for molecular modelers is quickly and effectively visualizing complex molecular systems. These systems often involve various components like ligands, receptors, and structural elements, each requiring distinct visual representations and color schemes for clear understanding. Instead of manually setting up these representations, SAMSON offers a powerful solution: Visual Presets.
Why Visual Presets Make Life Easier for Molecular Modelers
In SAMSON, Visual Presets allow you to apply multiple visual representations and color schemes to molecular systems in just a few clicks. They enable modelers to save time and effort by eliminating the repetitive process of individually configuring different visualizations for specific parts of a molecular system. Whether you’re focusing on protein-ligand interactions or detailed atomic structures, Visual Presets streamline the process and help you focus on your analysis.
Applying Visual Presets
Accessing and using Visual Presets is remarkably simple. Just navigate to either Home > Visual preset or Visualization > Visual preset in SAMSON. From there, you can select and apply existing presets to your molecular system.
As an example, here’s how the Protein-ligand visual preset looks when applied to the protein structure with PDB code 1AA1:
With this preset, the selected protein and ligand are instantly showcased with specific visual and color representations, making it easier to analyze interactions and structural features.
Customization: Create Your Own Visual Presets
If the default presets don’t entirely fit your needs, SAMSON allows you to create and customize your own Visual Presets using the Visual Preset Editor. Here’s how you can do it:
- Navigate to Home > Visual preset > Create…, or Visualization > Visual preset > Create….
- Click the
“Add step” button to define steps for your visual preset. Each step allows you to perform four key actions: - Define a node selection (e.g., select “Receptor,” “Ligands,” or any custom specification).
- Specify actions to apply to the selection (e.g., “Hide,” “Label atoms,” or “Zoom on selection”).
- Choose a visual model (e.g., “Van der Waals,” “Ribbons,” etc.).
- Select a color scheme (e.g., “Per chain,” “Constant color,” or custom schemes).
- Repeat these steps to create a sequence that perfectly matches your visualization goals. For more customization, you can modify color palettes or reorder steps as needed.

Sharing and Saving Your Work
Once you’re satisfied with your custom Visual Presets, you can save them for future use. Saved presets are loaded alongside default ones each time you open SAMSON, ensuring your personalized visualizations are always at your fingertips. Additionally, you have the option to share your presets for potential inclusion in SAMSON’s default preset list by providing feedback through the Send feedback button in SAMSON.
Conclusion
SAMSON’s Visual Presets are an invaluable tool for molecular modelers who need clarity and efficiency in visualizing and analyzing complex systems. By leveraging default and customizable presets, you can save time, enhance your productivity, and create professional-grade molecular visualizations effortlessly.
