For molecular modelers, effectively visualizing complex nanosystems can often feel overwhelming. Whether you’re analyzing a protein’s secondary structure, electron density, or electrostatic fields, the information can be vast and hard to parse at a glance. SAMSON’s visual models provide an efficient way to represent molecular structures and properties in a visually comprehensive manner, helping you make sense of intricate data.
What Are Visual Models?
Visual models in SAMSON are specialized tools that create graphical representations of nanosystems. For example, they can render secondary structures of proteins, generate surfaces such as Gaussian or isosurfaces, or even illustrate volumetric representations of physical fields like electron densities or electrostatic potentials.
By leveraging different types of visual models, molecular modelers can tailor their workflows to highlight key details of their systems. They enable users to pinpoint atoms, residues, or chains, providing clarity at every level of molecular organization.
Getting Started with Visual Models
SAMSON offers a variety of preloaded visual models, which can be accessed easily within the application. To apply a visual model, you can:
- Use the context toolbar menu for the selected nodes.
- Navigate to Visualization > Add > Visual Model in the top menu.
- Use the shortcut Ctrl/Cmd + Shift + V.
Visual models can be applied globally to the entire document or locally to specific selected nodes, allowing for precise, targeted analysis.
Customizing Visual Representations
Some visual models offer customizable parameters, allowing you to fine-tune their appearance for your particular use case. For instance, you can modify the settings for a secondary structure visual model through the Inspector:
- Select the visual model in the Document view.
- Click on Inspect in the context menu to adjust parameters.
Why Use Visual Models?
Visual models do more than just make nanosystems look appealing—they improve your workflow and understanding of your system’s structure and properties dramatically. By applying these graphical representations:
- You can visually inspect and select specific components, such as residues within a solvent-excluded surface, enabling quicker analysis.
- You can highlight areas of interest dynamically, depending on the selection filters in use.
An example is shown below, where highlighting residues on a solvent-excluded surface provides clarity for further analysis:
Extending Functionality
While SAMSON provides a robust collection of visual models by default, you can extend its capabilities even further by exploring the extensions available on SAMSON Connect. For those looking to develop their custom tools, SAMSON also supports extension generation. Detailed guides for developing your models are available at the Extension Generator resource.
