Simplifying Label Node Management with NSL Attributes

Working on molecular models often requires assigning and managing labels on specific nodes. Whether you’re highlighting specific areas or controlling visibility, making these tasks as seamless as possible can save invaluable time and resources.

SAMSON’s Label Attribute Space within the Node Specification Language (NSL) brings order to this complexity. It comes packed with useful tools specifically designed to make managing these labels simpler and more intuitive.

Understanding the Label Attribute Space

The label attribute space is designed exclusively for label nodes and uses la as its short name. Key attributes include names, selection states, visibility flags, and others, allowing modelers to define and filter labels efficiently.

The table below summarizes the primary label attributes:

Attribute Name	Short Name	Possible Values	Examples
hidden	`h`	`true`, `false`	`la.h` `not la.h`
name	`n`	Strings in quotes	`la.n "A"` `la.n "L*"`
selected	(None available)	`true`, `false`	`la.selected` `not la.selected`
selectionFlag	`sf`	`true`, `false`	`la.sf false` `la.sf`
visibilityFlag	`vf`	`true`, `false`	`la.vf false` `la.vf`
visible	`v`	`true`, `false`	`la.v` `not la.v`

Key Attribute Highlights

Here are some of the most impactful label attributes in practice:

hidden (h): Useful for toggling the invisibility of a label. Using la.h helps filter hidden nodes, while not la.h shows visible ones.
name (n): Allows targeting nodes by string names. Utilize wildcard operators for even more versatility, e.g., la.n "L*" matches nodes starting with “L”.
visible (v): Differentiates explicitly visible labels from those temporarily hidden via visibility flags or parent nodes. not la.v isolates invisible nodes efficiently.
selectionFlag (sf): Confirms whether a label is flagged as part of the current selection. Use expressions such as la.sf false to exclude specific selections programmatically.

Why It Matters

For molecular modelers, clarity is critical. Noticing even the smallest details can strongly influence research outcomes. NSL’s label management tools simplify workflows, enabling users to filter, search, and modify node attributes effortlessly.

Instead of wresting with tedious, manual processes, these flexible attributes empower scientists and researchers to focus on what truly matters: advancing their molecular designs.
