Simplifying Molecular Design with Note Attributes in SAMSON NSL

For molecular modelers, efficiency in organizing, selecting, and visualizing molecular nodes is essential. The Note Attributes feature in SAMSON’s Node Specification Language (NSL) provides a powerful approach to streamline these tasks. Let’s explore how note attributes work, their capabilities, and why they can be pivotal in improving your modeling workflows.

What Are Note Attributes?

Note attributes in SAMSON are a specialized set of attributes within the note attribute space (with the short name nt). They are specifically designed to match and manipulate note nodes. These attributes can refine targeting and filtering, allowing users to manage molecular notes in their projects with remarkable precision.

Inherited Attributes: Note attributes inherit their definitions and functionality from more general node attributes. However, the note-specific namespace ensures that they can be applied exclusively to notes.

Key Note Attributes

Below is a concise overview of the most critical note attributes—which are intuitive to use and greatly enhance efficiency when working on molecular designs:

  • hidden (h): Determines whether a note is hidden. Possible values: true or false.
  • name (n): Refers to the name of the note as a quoted string (e.g., "A" or "L*").
  • selected: Indicates whether a note is selected. This attribute does not have a short name. Values: true or false.
  • selectionFlag (sf): Marks whether a note has a selection flag enabled. Values: true or false.
  • visibilityFlag (vf): Determines whether a visibility flag is active. Values include true and false.
  • visible (v): Indicates whether a note is visible in the current view. Values: true or false.

Examples of Usage

The specificity of note attributes is a valuable tool for complex molecular designs. Let’s break down a couple of practical examples:

  • Filtering visible notes: To target only visible notes, you can use nt.v, while not nt.v ensures you focus on non-visible nodes.
  • Naming with patterns: Searching for notes with a specific name, such as "A", would involve nt.n "A". Wildcards are supported too, for example, nt.n "L*" to find all notes starting with the letter L.

By mastering such syntax, you can quickly organize and manipulate molecular nodes in your project workspace.

Conclusion

Note attributes in SAMSON’s NSL empower molecular modelers to manage and interact with note nodes effectively. Whether you’re filtering for visibility or matching specific patterns, these attributes provide robust functionality that saves time and enhances productivity.
