Understanding Label Node Attributes in SAMSON

Molecular modeling can be a complex task, often requiring precise manipulations and customizations of structures. Many users, especially those dealing with large molecular systems, face challenges in efficiently organizing and visually managing node data. This is where SAMSON’s label attributes come into play, offering a streamlined way to handle label nodes effectively.

In SAMSON, label nodes are a special category of nodes that enable users to apply labels to structures. These labels can further be refined and controlled using label attributes provided in the label attribute space (with the short name la). This blog post dives into the key label attributes and explains how they can enhance molecular manipulation workflows.

Overview of Key Label Attributes

The label attribute space provides several attributes inherited from the node attribute space. Here are the most important ones:

  • hidden (Short Name: h): Allows you to hide or show specific labels. Possible values are true and false. For example, la.h will return labels marked as hidden, while not la.h will find those that are visible.
  • name (Short Name: n): Enables you to filter labels by their names, which must be specified as strings in quotes. Use cases include querying a specific label with la.n "A" or finding labels matching a pattern such as la.n "L*".
  • selected: Identifies whether a label is selected (true or false). Examples include using la.selected to find selected labels or not la.selected to query the ones that are not selected. Note: This attribute does not have a short name.
  • selectionFlag (Short Name: sf): Similar to selected, this flag can determine whether a label has been marked with certain selection identifiers. For example, use la.sf false to find unselected nodes.
  • visibilityFlag (Short Name: vf): Defines whether a label can be toggled for visibility. Query this with la.vf false to find labels that are not visible or simply use la.vf for visible ones.
  • visible (Short Name: v): An intuitive attribute to check the visibility status of labels. Use la.v for visible labels and not la.v to query hidden ones.

Practical Use Cases

By leveraging the label attribute space, you can efficiently organize and filter label nodes in large and complex models. For instance:

  • Identify and isolate visible or hidden labels to streamline visual analysis of structures.
  • Use name patterns to search for and retrieve specific labels more efficiently.
  • Toggle selection flags for labels to highlight or group them for advanced operations.

These attributes provide a systematic approach to manage molecular data, saving valuable time and ensuring clarity, especially when working with extensive datasets.
