When working on molecular modeling and design, a clear and effective visual representation of nanosystems is essential. Visualizing molecules, proteins, and their complex interactions allows researchers to analyze structures and identify key patterns. However, tuning such graphical representations can often seem complicated. SAMSON offers a practical solution with its Visual Models, making graphical customization accessible and efficient.
What are Visual Models?
Visual models in SAMSON are tools to create graphical representations of nanosystems, from proteins' secondary structure representations to volumetric maps of electron densities or electrostatic fields. These representations make it possible to explore molecular features visually, helping tailor views to meet the needs of a specific study.
Why Molecular Modelers Love Visual Models
When conducting research, understanding molecular structures at a glance—be it atom locations, protein surfaces, or densities—can be invaluable. Here are some reasons why visual models improve molecular modeling workflows in SAMSON:
- Customizable views: SAMSON offers default visual models such as secondary structure representations and Gaussian surfaces. Additionally, researchers can customize and expand the available options by downloading extensions on SAMSON Connect.
- Focus on specific nodes: By applying visual models to selected structures or entire documents, users can showcase specific nanosystem features or explore the entire system holistically.
- Enhance workflows with shortcuts: Visual models can be applied rapidly using the context toolbar, from the visualization menu, or with the keyboard shortcut
Ctrl/Cmd+Shift+V.
Fine-Tuning Visualizations with the Inspector
If you need even more control, SAMSON lets you adjust parameters for certain visual models within the Inspector:
- First, locate the applied visual model in the Document View.
- Select it and choose Inspect via the context menu.
- Modify options like surface resolution and display filters to meet your visualization needs optimally.
This feature is particularly useful for generating publication-ready images or preparing presentations that perfectly highlight molecular features.
Applying Advanced Features
Default visual models in SAMSON also enable atom, residue, or chain selection through graphical surfaces. For instance, the Solvent-Excluded Surface visualization makes it simple to highlight and select key residues. Combined with SAMSON’s versatile selection filters, you can isolate specific regions of interest effectively.
Expand Your Capabilities
SAMSON not only equips you with default visual models but also allows developers to create their own. If you feel inspired to build custom functionalities, the Extension Generator and the Documentation Center provide all the tools and guidance you need.
