Molecular modelers often grapple with the challenge of visualizing complex molecular systems in an effective and time-saving manner. Customizing individual visual representations and applying appropriate color schemes can be both tedious and resource-intensive, especially for large systems. If you’ve ever felt this pain point in your workflow, SAMSON’s Visual Presets offer an elegant solution.
What Are Visual Presets?
Visual Presets in SAMSON allow you to quickly apply multiple visual representations and color schemes to molecular systems. Instead of manually configuring each aspect of a molecular visualization, you can choose from ready-made presets or design your own customized ones. This approach not only saves time but also ensures that your visualizations communicate molecular details clearly and effectively.
The Basics of Applying Visual Presets
One of the simplest ways to use Visual Presets is by accessing them from either the Home or Visualization menu in SAMSON. Once selected, you can apply a preset to an entire molecular document or specific selected nodes. For example, the Protein-Ligand preset can transform a representation of the PDB structure 1AA1 into a clearer visual format that highlights essential molecular interactions. Here’s what it might look like:

When you apply a preset, SAMSON generates a folder in your document containing the visual models and node groups created by the preset. This structured organization keeps your workspace manageable and reproducible.
Customizing and Creating Your Own Visual Presets
While SAMSON comes with a default set of presets, many users may find it beneficial to create variations tailored to their specific projects. Using the Visual Preset Editor, you can either modify existing presets or build entirely new ones from scratch:
- Add preset steps: Each step targets specific nodes (“Receptor,” “Ligands,” etc.) and optionally applies actions (e.g., hiding, labeling), visual models (e.g., ribbons, Van der Waals), and color schemes.
- Flexible selector customization: If the default node selections don’t meet your needs, you can define your own using the Node Specification Language (NSL).
- Enhanced aesthetics: Fine-tune the visual output by choosing specific color schemes (e.g., per element, constant colors) and customizing color palettes.
Here’s what the Visual Preset Editor looks like in action:

This level of control ensures that your visualizations align seamlessly with your presentation or research objectives.
Key Benefits of Visual Presets
- Save significant setup time by applying predefined or custom styles in seconds.
- Achieve consistency in molecular visualizations, especially when preparing professional presentations or publications.
- Organize your workspace efficiently with preset-generated folders of visual models and groups.
Whether it’s highlighting specific interactions in a protein-ligand complex or visualizing structural details with ribbons and atom labels, Visual Presets make molecular modeling more intuitive and productive.
