For molecular modelers looking to communicate complex structural details effectively, customizing labels can be a game-changer. Whether you are analyzing molecular systems or preparing stunning visual presentations, SAMSON’s labeling tools can help you present essential details clearly and professionally. Let’s explore how you can tailor labels to suit your analysis and presentation needs.
Why Customize Labels?
Labels in SAMSON are more than just text annotations. These can include names of nodes (like atoms or residues), descriptive texts for grouped nodes, or even measurement results. By customizing their appearance, you can make critical information stand out, ensure readability, and adapt labels to the context of your analysis. Enhanced visibility and presentation clarity are key to better communication of your findings.
Changing Label Fonts
Tailoring the font of your labels is straightforward and can significantly improve the appearance of your molecular visualization. To change fonts:
- Open the Preferences (
Rendering > Labels) to set a default font for all labels without specific customization. You can also define the number of decimal places for measurements such as angles or distances in this menu. - For specific labels, select them, open the Inspector, and click Choose font…. You can either modify the font for one label or select multiple labels and choose to Edit all selected nodes.
If you want to reset your changes and revert to the default font, simply select the labels, go to the Inspector, and double-click on the Font setting. This resets the label fonts to the global preferences.

Colorizing Labels
Color-coded labels are an excellent way to convey structure-specific information or differentiate between regions of interest. Here’s how you can add a splash of color to your labels:
- In the Document view, click on a label and navigate to Color > Constant. Choose a preferred color in the pop-up dialog.
- Alternatively, select a label and use the Color option in the Visualization toolbar.
- You can also refine colors in the Inspector, specifying custom hues for individual or grouped labels.
Need to reset a label’s color? You can do this easily through the Inspector by clicking the X button (next to Text color). Similarly, options in the Color menu allow you to restore default colors.

Tips for Effective Label Customization
When customizing labels, remember the following:
- Consistency is key: Use similar fonts and colors for related labels to maintain visual harmony.
- Highlight your key points: Use contrasting colors or bold fonts for labels that showcase important structural details or measurements.
- Test for readability: Make sure your labels remain legible at various zoom levels and viewing angles.
By following these steps, you can create visually appealing molecular visualizations that not only enhance the clarity of your models but also make your presentations stand out. SAMSON’s tools provide a robust, intuitive way to personalize labels, empowering molecular modelers to communicate data more effectively.
