Mastering Note Attributes in SAMSON’s Node Specification Language (NSL)

When working on molecular models, organization is critical. Managing and analyzing complex molecular data often demands clear structures and tailored metadata. This is where the note attributes in SAMSON’s Node Specification Language (NSL) can make a big difference for researchers.

The note attribute space is specifically designed for note nodes, allowing users to structure their annotations, visibility, and selection settings effectively. Let’s take a deeper look at what these attributes offer and how you can leverage them to save time and streamline your workflows.

Understanding Note Attributes

Note attributes belong to the attribute space note, abbreviated as nt. These attributes allow you to manage metadata about note nodes, which are widely used for annotation purposes during molecular modeling. From visibility settings to naming conventions, these attributes can help you maintain optimal clarity and accessibility in your models.

Key Attributes

Here are some of the most important note attributes you can use:

Attribute name	Short name	Possible values	Examples
hidden	`h`	`true`, `false`	`nt.h` `not nt.h`
name	`n`	strings in quotes	`nt.n "A"` `nt.n "L*"`
selected		`true`, `false`	`nt.selected` `not nt.selected`
selectionFlag	`sf`	`true`, `false`	`nt.sf false` `nt.sf`
visibilityFlag	`vf`	`true`, `false`	`nt.vf false` `nt.vf`
visible	`v`	`true`, `false`	`nt.v` `not nt.v`

For instance, the name attribute helps you assign or find specific strings within your note nodes. This can be critical when designing highly detailed systems or when coordinating across teams. Boolean attributes like hidden and visible allow users to toggle what is displayed during analyses, contributing to a less cluttered workspace.

Inherited Attributes

Note attributes also include some inherited settings from the general node attribute space. This makes it easier to apply consistent rules across both notes and other node categories:

hidden: Whether the note is hidden (true) or not (false).
visibilityFlag: Controls visibility settings.
selectionFlag: Determines selection status.
selected: You can programmatically define whether a note is selected at a given time.

Practical Tips for Using Note Attributes

When using SAMSON for molecular modeling, note attributes shine when multiple models, annotations, or notes need to be cross-referenced. For example:

Use nt.h to identify and toggle hidden attributes for cleaner visualization during presentations.
Apply patterns within nt.n to name your nodes methodically, making data search significantly easier with expressions like nt.n "Label*".
For selective focus during calculations, leverage nt.selected or nt.sf effectively.

These functionalities open up a wealth of possibilities for organizing and interacting with your molecular designs in SAMSON.
