Streamline Molecular Visualization with Visual Presets
For molecular modelers, one of the most time-consuming challenges is creating clear, professional visualizations of molecular systems. Whether you’re presenting a complex protein-ligand interaction or exploring the intricate structures of biomolecules, setting up visual representations manually can feel like a daunting task. But did you know SAMSON provides a way to simplify this process in just a few clicks? Meet Visual Presets.
Visual Presets are a powerful SAMSON feature that allows you to apply predefined visual representations and color schemes to molecular systems quickly. This blog post takes you step-by-step through the process of applying visual presets so you can focus more on analyzing and less on configuring settings.
What Are Visual Presets?
Think of Visual Presets as customizable stylesheets for molecular visualization. These presets combine multiple visual representation styles (e.g., ribbons, van der Waals surfaces) and color schemes into a single selection. This enables you to instantly switch between different visualization styles tailored for specific cases, such as protein-ligand interactions, nucleic acids, or molecular assemblies.
How to Apply Visual Presets
Applying visual presets in SAMSON is quick and easy. Follow these steps:
- Go to the Home > Visual preset or Visualization > Visual preset menu.
- Choose one of the available visual presets from the list.
Here’s an example of how the Protein-ligand visual preset transforms a molecular structure (in this case, PDB code 1AA1):
Pro Tip: If nothing is selected in your molecular system, the visual preset will be applied to the entire document. Otherwise, it will only affect the selected nodes. Once applied, the preset creates a folder in the document to organize visual models and node groups associated with it.
Why Use Visual Presets?
Using visual presets isn’t just about saving time—it also ensures consistent, high-quality visualizations. For example, the Protein-ligand preset uses a combination of ribbons for proteins and licorice models for ligands, paired with color schemes for quick interpretation of system components. These presets are especially useful when:
- Presenting results to colleagues or collaborators
- Creating publication-ready images
- Exploring complex molecular interactions
Beyond Applying: Creating Your Own Visual Presets
If the default presets don’t match your requirements, SAMSON gives you the freedom to create custom visual presets. Whether you’re modifying an existing preset or building one from scratch, you can fully personalize:
- Node selections (e.g., ligands, water molecules)
- Visualization styles (e.g., van der Waals, ribbons, licorice)
- Color schemes (e.g., per chain, per element)
- Actions (e.g., labeling atoms, zooming on selections)
To get started, simply use the Visual Preset Editor, available through Home > Visual preset > Create… or Visualization > Visual preset > Create…. Explore the ways this feature lets you streamline and standardize how you visualize molecular systems.
