Understanding Visual Model Attributes for Molecular Design

For molecular modelers, the visual representation of models is key to understanding and analyzing structures effectively. Within SAMSON, the integrative molecular design platform, managing how nodes are visually displayed can be streamlined using Visual Model attributes of the Node Specification Language (NSL). These attributes help control the visibility, material ownership, and naming of visual model nodes in your molecular projects, supporting better organization and interpretation of data.

What Are Visual Model Attributes?

Visual Model attributes are part of the visualModel attribute space (short name: vm). They apply specifically to visual model nodes and allow users to define key properties such as whether a visual model has material, is visible, is hidden, or selected. These attributes inherit properties from the more general node attribute space but are tailored for visual representation adjustments.

How Can Visual Model Attributes Simplify Your Workflow?

Let’s dive into some of the key attributes and how they can help streamline your molecular modeling workflow:

  • hasMaterial (vm.hm): This attribute determines if a visual model has a material associated with it. For example:
    • vm.hm: Returns true if the visual model has material.
    • not vm.hm: Ensures the visual model doesn’t have associated material.
  • hidden (vm.h): This specifies whether a visual model is hidden. It’s an efficient way to toggle the visibility of nodes for better model clarity. For instance:
    • vm.h: The node is hidden.
    • not vm.h: The node is visible.
  • name (vm.n): This allows you to assign or query the name of a visual model. Useful for searching and managing large sets of nodes:
    • vm.n "A": Matches a visual model named “A”.
    • vm.n "L*": Matches a visual model with names starting with “L”.
  • ownsMaterial (vm.om): Indicates whether a material is owned by a visual model. Example usage:
    • vm.om: Returns true for ownership.
  • selected: Determines if a visual model is currently selected. Unlike the equivalent node-level selected attribute, this doesn’t have a short name. Example:
    • vm.selected: The node is selected.
    • not vm.selected: The node is not selected.
  • visibilityFlag (vm.vf): A more specific control for toggling node visibility.
    • vm.vf false: Hides the node.
    • vm.vf: The node remains visible.

Practical Example

Consider a case where you are analyzing a complex molecular system with multiple visual models. By using the vm.h and vm.v attributes, you can quickly hide or display specific sections of your model, making it easier to focus on areas of interest while ignoring less relevant parts. Additionally, by using vm.n, you can filter nodes by name and apply targeted operations to select a subset of relevant data.

Why Should You Explore These Attributes?

Visual Model attributes in SAMSON enable molecular modelers to customize their representations to suit specific needs. With properties like visibility toggles, material ownership checks, and naming systems, users can organize their data more effectively and improve their modeling efficiency.
