For molecular modelers, precise and intuitive visualization of nanosystems is key to understanding complex structures and systems. SAMSON’s Visual Models offer a powerful way to bring clarity to your work, helping you display nanosystems in various graphical formats suited to the task at hand. In this blog post, we’ll dive into how you can use visual models in SAMSON to enhance your molecular modeling experience.
What are Visual Models?
Visual models in SAMSON provide graphical representations of nanosystems. These representations can help you interpret data, communicate results, and identify critical features of your models. Examples of visual models include:
- Secondary structure representations of proteins
- Gaussian surfaces
- Isosurfaces of electron densities
- Volumetric representations of electrostatic fields
SAMSON includes a set of default visual models, and more can be added through SAMSON Connect or developed as extensions.
How to Apply Visual Models
Visual models can be applied to individual nodes or entire nanosystems. Here’s how:
- Use the context toolbar for selected nodes
- Navigate to Visualization > Add > Visual Model in the menu
- Use the shortcut: Ctrl/Cmd + Shift + V
The default models make it easy to highlight and select specific structures such as atoms, residues, or chains. For instance, you can highlight residues directly on surfaces using selection filters.
Fine-Tune Your Visual Models
Many visual models come with customizable parameters, allowing you to tailor the visualization to your needs. To modify these parameters:
- Select the visual model in the Document View
- Right-click and select Inspect in the context menu
- Adjust parameters in the Inspector
For example, in the case of secondary structure visual models, you can change display styles, colors, and other parameters via the Inspector panel. This flexibility allows molecular modelers to focus on specific features critical to their research.
Develop Your Own Visual Models
If the default options don’t meet your needs, SAMSON supports extension development. You can create custom visual models by following the Extension Generator Documentation. Whether it’s for novel volumetric representations or completely new visualization tools, SAMSON adapts to your creativity.
Conclusion
Visual models are an essential tool for anyone working with molecular systems. They empower researchers to break down complex nanosystems into clear, meaningful representations that drive insights and discovery.
