Molecular modeling is a domain with endless complexities, and anything that simplifies workflows can feel like a revelation. SAMSON, the integrative molecular design platform, provides a powerful toolset that includes the Node Specification Language (NSL), allowing users to efficiently query, filter, and manage molecular nodes. One important subset of NSL is the note attribute space—a toolkit specialized for working with note nodes. Here, we’ll dive into what note attributes are and how they might simplify your modeling tasks.
What Are Note Attributes?
The note attribute space (short name: nt) is designed specifically for note nodes. These attributes can be used to refine operations on note nodes, such as filtering them based on visibility, selection status, or name patterns. If you’re consistently working with annotated nodes or specific layers of structural information, this attribute space can streamline operations within SAMSON.
Below is a summarized table of key note attributes:
| Attribute | Short Name | Possible Values | Examples |
|---|---|---|---|
| hidden | h |
true, false |
nt.hnot nt.h |
| name | n |
strings in quotes | nt.n "A"nt.n "L*" |
| selectionFlag | sf |
true, false |
nt.sf falsent.sf |
Common Use Cases
Molecular modelers often struggle to manage complex datasets, which include various layers of annotations, visibility flags, and selection states. The note attributes provide an effective querying mechanism to alleviate this pain:
- Filtering based on attributes: Use the attribute
nt.hto isolate hidden notes or leveragent.vfor selecting visible ones. - Organizing intricate models: Simplify model refinement by using
nt.sfto work with a specific selection flag, aligning complex layers. - Pattern-based querying: Filter notes by their names through expressions like
nt.n "Layer*"to work specifically with annotated layers in hierarchical structures.
Quick Example: Simplifying Visibility Management
Imagine you are working on a molecular model with numerous annotations that clutter your workspace. You could hide all notes with:
nt.v false
If you later want to review those same annotations, use:
nt.v
This two-step visibility adjustment ensures that visual clutter doesn’t slow you down, keeping the modeling workspace neat and focused.

The note attributes are inherited from the general node attribute space, making them intuitive for anyone familiar with NSL. Exploring these attributes unlocks extensive workflows and tailors SAMSON to your modeling needs.
