Streamlining Molecular Model Notes: A Guide to Note Attributes in SAMSON

For molecular modelers, managing and organizing notes effectively while working on complex systems can be a challenge. Whether you’re annotating specific nodes, tracking visibility states, or setting up relevant selections, SAMSON’s Note attributes in its Node Specification Language (NSL) provide a robust solution for improving your workflow.

What Are Note Attributes?

Note attributes belong to a specific attribute space in SAMSON’s NSL, designed to work with ‘note nodes.’ They allow users to customize node visibility, manipulate annotations, and filter nodes for clarity and focus. These attributes inherit properties from the broader ‘node’ attribute space, making them both versatile and powerful tools for project annotation and exploration in molecular design.

Key Attributes Breakdown

The note attribute space (nt) includes the following attributes:

  • Hidden (nt.h): Use this to control whether a node should be hidden or not. Valid values are true or false, making it useful for quickly decluttering your workspace.
  • Name (nt.n): Label your nodes with descriptive names to make searching efficient. You can use quoted strings, such as nt.n "A", or patterns like nt.n "L*" to filter multiple nodes.
  • Selected: Determines whether a node is actively selected. Examples include nt.selected or not nt.selected. Note that there is no short name for this attribute.
  • Selection Flag (nt.sf): This flag works similarly to Selected, but serves more specific logical cases for workflow refinements.
  • Visibility Flag (nt.vf): Like the Hidden attribute, the visibility flag is a critical toggle for simplifying complex node structures.
  • Visible (nt.v): A straightforward way to toggle node visibility. Examples include nt.v and not nt.v.

Improving Your Workflow

Imagine managing a network of hundreds of nodes in a molecular model. Without proper tools, ensuring that only the relevant nodes are displayed or annotated could quickly become overwhelming. Note attributes address these pains by allowing you to use precise expressions that fit seamlessly into your modeling routines.

For instance:

  • Use nt.h to hide intermediary steps in your process without deleting them.
  • Apply nt.n to dynamically search for and organize nodes with logical naming conventions or wildcard patterns.
  • Toggle the visibility of nodes with nt.v to zoom in on specific areas of your molecular model.

Going Deeper

Each attribute is thoughtfully designed to either simplify your workspace or make your annotations more meaningful. For advanced users, combining these attributes with SAMSON’s scripting and filtering features unlocks even greater levels of customization, letting you focus on molecular designs that matter most.
