When working on intricate molecular models, clarity is often paramount. Labels in SAMSON are a powerful tool that molecular modelers can use to highlight critical structural elements and describe or measure various groups of nodes. But what do you do when those labels clutter your workspace or disappear at inconvenient times? Understanding how to control label visibility and customize appearance can optimize your workflow for both analysis and presentation.
Why Managing Label Visibility Matters
Labels are extremely helpful for annotating molecular structures, whether you’re indicating atomic residues, marking specific atoms, or explaining groupings. However, as you zoom in and out of a complex model, managing the automatic display of labels can become tricky. Without proper customization, labels can obscure details or leave out important annotations at various zoom levels.
Making Labels Work for You
In SAMSON, label visibility automatically adjusts to the zoom level of your model. Smaller nodes, like atoms, lose their labels when zooming out, while larger nodes, such as molecules, show theirs. You can fine-tune these settings to ensure that crucial information is always visible regardless of your viewport zoom level.
Here’s how to modify this:
- Select a label in the Document view or the Viewport.
- Open the Inspector.
- You’ll find options to change the maximum and minimum display radii. Adjust these parameters to control when the label appears as you zoom in or out on the model.
This adjustment makes display behavior consistent with your focus, ensuring the visibility of essential details when needed, without unnecessary clutter.

Customizing Font and Colors for Better Readability
Another major pain point in creating molecular models is label readability. The ability to distinguish between annotations quickly can save time and reduce errors.
In SAMSON, you can customize label fonts and colors to match your project’s unique needs:
- Fonts: Modify fonts in the Preferences under Rendering > Labels for a universal style, or make targeted changes to individual or group labels through the Inspector. Options include editing font sizes, styles, and decimal places for measurements. To reset to default fonts, double-click the Font setting within the Inspector.

- Colors: To make your labels visually intuitive, adjust their colors. Use the context toolbar in the Document view or the Inspector. Select Color > Constant and pick your desired shade. Transparency can also be fine-tuned in the Inspector, providing flexibility for layered visualizations. Resetting to default color settings is also a straightforward option.

A Smoother Workflow
By mastering label visibility, font, and color options in SAMSON, you can strike the perfect balance between detailed annotation and a clean workspace. Whether you’re preparing a high-stakes presentation or diving deep into structure analysis, tailoring your labels will ensure that the information you need is easy to read and intuitively arranged within your model.
