For molecular modelers, visualization is key. Complex nanosystems can be daunting to analyze without the right tools. If you’ve ever struggled to visually represent intricate molecular structures or fields, SAMSON has you covered with its powerful Visual Models. Let’s explore how these models can make your work clearer and more actionable!
What are Visual Models?
Visual models in SAMSON take your molecular systems beyond structural data by offering dynamic graphical representations. They enable you to better understand and highlight features such as secondary structures, surfaces, fields, and much more. For example, you can easily generate a Gaussian surface, represent an electrostatic field as a volumetric map, or even visualize isosurfaces of electron density.
Above is an example of some default visual models available in SAMSON. This variety allows you to tailor the appearance of your nanosystems to suit your needs.
Applying Visual Models
The flexibility of visual models lies in their application. You can either apply them to selected nodes of your molecular system or to the entire document if no specific part is selected. Here’s how:
- Context Toolbar Menu: Select nodes and use the context toolbar menu to add models.
- Menu Navigation: Navigate to Visualization > Add > Visual Model to apply them manually.
- Keyboard Shortcut: Use
Ctrl (Cmd) + Shift + Vfor quicker application.
To dive deeper into how to apply visual models, check out the Visualizing section in the documentation.
Fine-Tuning Your Visual Models
Customizing your visual models is straightforward in SAMSON. For instance, after applying a visual model, you can modify its visualization parameters:
- Locate the visual model in the Document view.
- Right-click and select Inspect to fine-tune in the Inspector.
This feature is particularly useful for tailoring how atoms, residues, chains, or surfaces are displayed based on your current selection filters.
For example, the above image shows how secondary structure visual model parameters can be adjusted using the Inspector, giving you full control.
Highlighting and Selection
Highlighting and selecting features within visual models is incredibly intuitive. Using elements like solvent excluded surfaces, you can easily detect and choose specific residues or other components based on your active selection filters:
This capability brings clarity to your analysis, helping you focus on the molecular details that matter most.
Taking it Further
If you’re up for building your own visual models for even more customized representations, SAMSON has robust documentation to guide you. Refer to the extension generation tools to create new models that suit your unique needs.
Visual models are a vital part of SAMSON’s toolkit, streamlining your ability to analyze, communicate, and iterate on your molecular designs with ease and precision. To explore the full capabilities of visual models and their applications, visit the original documentation page.
