Accurate measurements are at the heart of many molecular modeling tasks, whether you’re analyzing bond lengths, angles, or torsional configurations. In SAMSON, the integrative molecular design platform, the Measure editor is your go-to tool for precise and informative measurements. But did you know that saving measurements as labels can make your workflow even more efficient and insightful? In this blog post, we’ll dive into why and how to save measurements as labels, along with tips to customize their appearance.
Why Save Measurements as Labels?
While temporary measurements might seem sufficient for quick evaluations, saving them as labels in your document offers significant advantages:
- Persistence: Saved labels remain visible and accessible across sessions, eliminating the need to re-measure after closing and reopening a project.
- Clarity: Measurements tied to the document act as annotations that adjust visibility based on zoom level, ensuring a cleaner view of your model.
- Traceability: Labels connect directly to the atoms involved, enabling users to inspect and refine the associated nodes through the Inspector.
How to Save Measurements as Labels
Using the Measure editor is simple. Start by clicking on the specific atoms or bonds in your molecular model:
- Bond: Click on a bond to display its length.
- Two atoms: Click on two atoms to measure the distance between them.
- Three atoms: Click on three atoms to calculate the angle they form.
- Four atoms: Click on four atoms to determine the torsion angle between them.
Once the measurement appears, press Enter to save it as a label. This step converts the temporary measurement into a permanent, editable component of your document.
Customizing Measurement Labels
Labels in SAMSON aren’t static. You can tailor their appearance to enhance visualization:
- Colors: Modify the line, angle, or plane colors through the Inspector. For example, you can assign distinct colors to emphasize different types of measurements.
- Font: Adjust the text font and size for labels individually via the Inspector or globally for all labels in Preferences > Rendering > Labels.
- Resetting defaults: Return to default colors and formatting by double-clicking on associated fields in the Inspector or clicking the “clear” button next to text color settings.
Customizing labels makes it easier to visually differentiate measurements, streamlining your workflow in complex systems.
Labels for Advanced Analysis
Saved labels aren’t just static markers. They adapt to changes dynamically:
- When atoms move (e.g., during interactive minimization or using Move editors), labels update automatically to reflect modified distances and angles.
- Inspect labels in the Inspector to access additional projections, such as distances projected onto specific planes.
