Filter and Explore Your Molecular Visual Models Effectively

For molecular modelers managing complex structures, navigating and isolating specific visual models can be challenging. This is where the Visual Model attributes in SAMSON’s Node Specification Language (NSL) can help. These attributes offer a comprehensive way to interact with and filter visual models effectively, enabling you to focus on the details that matter most for your research or visualization goals.

Why Use Visual Model Attributes?

The visualModel attribute space in NSL allows molecular modelers to define attributes for nodes that represent visual models. Whether you want to check if a model has an associated material, alter visibility settings, or isolate specific nodes by their attributes, this functionality saves significant time and effort by narrowing your focus to relevant elements.

Key Attributes and Their Usage

The following are some critical Visual Model attributes:

  • hasMaterial (hm): Indicates whether a visual model has a material assigned. Possible values are true and false. Example usage: vm.hm to check if a material exists or not vm.hm to filter out such models.
  • hidden (h): Filters models that are hidden. Similarly, it accepts true and false. For instance, use vm.h to target hidden models.
  • name (n): Matches nodes by name, using string values in quotes. It even supports wildcards, e.g., vm.n "Ligand" or vm.n "L*".
  • visibilityFlag (vf): A boolean flag indicating whether a model’s visibility can be toggled. Example: Use vm.vf false to isolate models with fixed visibility.
  • selected: Finds models that are currently selected. This attribute doesn’t have a short name but provides powerful selection control using vm.selected or not vm.selected.

A Practical Example

Imagine working with a biological macromolecule composed of hundreds of visual elements. You want to quickly isolate visible components named “Ligand” that have assigned materials. Here’s how you could achieve it:

This query selects visual models that are visible (vm.v true), have materials (vm.hm), and match the name “Ligand” (vm.n "Ligand").

Benefits of Attribute-Based Filtering

This attribute system empowers researchers by offering:

  • Faster navigation through complex molecular structures.
  • Higher precision in visualizing and analyzing specific molecular features.
  • Time efficiency in creating tailored visualizations for publications or presentations.

Whether you are preparing a high-quality visual for a paper or analyzing simulation results, Visual Model attributes in SAMSON provide an efficient and flexible way to manage molecular data in real time.
