Visualizing complex molecular systems can often feel like an uphill battle. The intricate structures, multiple elements, and color schemes can make it overwhelming to find a clear and usable representation. If you’ve ever spent hours refining visual styles for your projects, SAMSON has a solution that can transform your workflow: Visual Presets.
What Are Visual Presets?
Visual Presets in SAMSON are pre-designed combinations of visual representations and color schemes that can be applied to molecular systems in just a few clicks. These presets simplify the visualization of complex structures and ensure that you can focus on analyzing your data rather than configuring aesthetics. Whether you’re working with proteins, ligands, or other molecular components, presets provide clear and professional visual results instantly.
How to Apply Visual Presets
Applying a Visual Preset is a breeze. Simply navigate to Home > Visual preset or Visualization > Visual preset from the SAMSON interface. From there, you can browse a variety of preset options and choose the one that best fits your needs.
For example, here’s how the Protein-ligand preset looks when applied to PDB code 1AA1:
It’s that simple! Whether you’re preparing for a presentation or just need a quick way to organize your molecular system, presets ensure you get a ready-to-analyze setup fast.
Customize or Create Your Own Visual Presets
If the existing presets don’t quite meet your needs, SAMSON allows you to customize or even build your own Visual Presets. Here’s how:
- Modify an existing preset: Select a preset, and tweak its steps, visual models, or color schemes.
- Create a new preset: Click the
button next to the presets list, and add steps that define selections, actions, visual models, and color schemes.
Each step in a Visual Preset offers flexibility, allowing you to:
- Define specific node selections (e.g., “Ligands,” “Receptor,” or custom-defined selections using SAMSON’s Node Specification Language).
- Apply actions such as labeling, hiding, or zooming on selections.
- Choose a visual model like “Ribbons,” “Licorice,” or “Van der Waals.”
- Select a specific color scheme, from constant color to per-chain and occupancy-based coloring.
SAMSON gives you the tools to tailor presets to your scientific or aesthetic needs and save them for repeated use. When you relaunch SAMSON, your saved custom presets will be ready to accelerate your work.
Why Use Visual Presets?
Speed and clarity are crucial for molecular modelers. Visual Presets offer:
- Time efficiency: Forget the time-consuming process of manual visualization configuration. Get it done in seconds.
- Consistency: Repeatedly apply the same representation style to similar systems for clear, reproducible results.
- Customization: Build tailored presets suited perfectly to your workflow and individual projects.
Visual Presets can also be shared with team members or collaborators, ensuring everyone is working with the same visualization standards.
