When working with molecular modeling in SAMSON, efficiently managing labels can greatly enhance your workflow. Labels serve as an excellent way to categorize and manage nodes in molecular models, and understanding how to use their attributes effectively is key to streamlining your tasks. In this blog post, we’ll take a closer look at label attributes in the Node Specification Language (NSL) and how you can harness their power.
What’s the ‘label’ Attribute Space?
In SAMSON, labels fall under the label attribute space, which is specifically designed to target label nodes. This attribute space has a short name, la, that you can use to create compact expressions, making it easier to manipulate label-related properties. What’s more, the label attribute space inherits several useful attributes from the generic node attribute space, tailored specifically for labels.
Commonly Used Label Attributes
Knowing the key label attributes can save you significant time when selecting, managing, or filtering labels. Let’s dive into the most commonly used attributes:
| Attribute | Description | Short Name | Examples |
|---|---|---|---|
| hidden | Checks whether the node is hidden. | h |
la.h, not la.h |
| name | Retrieves or specifies the name of the label. | n |
la.n "A", la.n "L*" |
| selected | Indicates whether the label is currently selected. | N/A (no short name) | la.selected, not la.selected |
| selectionFlag | Specifies the selection flag for the label. | sf |
la.sf, la.sf false |
| visibilityFlag | Toggles visibility flag for the label. | vf |
la.vf, la.vf false |
| visible | Indicates whether the label is visible. | v |
la.v, not la.v |
Practical Tips for Using Label Attributes
Here are a few practical ways molecular modelers can use these attributes:
- Filtering Labels: If you want to hide all labels starting with “Test,” use an expression like
la.n "Test*" and not la.v. - Selection Management: To quickly select all visible labels, use
la.v and not la.selected. - Organizing Complex Models: Manage the visibility of specific labels in dense molecular models by toggling the
visibilityFlag(la.vf) attribute based on your current focus.
Using these attributes effectively can save time, improve clarity, and make it easier to manage even the most complex molecular models.
Inherited Attributes
It’s worth noting that most label attributes are inherited from the more generic node attributes, but with a few adjustments. For example:
- The
selectionFlagandvisibilityFlagbehave the same way for both nodes and labels. - The
nameattribute allows you to query or specify label names just as you would for nodes. - The
selectedattribute for labels does not have a short name (unlike nodes).

Conclusion
Understanding and mastering label attributes in SAMSON can make molecular model management more efficient. Whether you’re working on visibility settings or organizing your labels with precision, these attributes are indispensable tools for any molecular modeler.
