When modeling molecules, precise measurements are critical for understanding and refining your structures. Whether you’re calculating bond lengths, angles, torsions, or distances between atoms, managing these measurements can quickly become overwhelming. Fortunately, SAMSON makes this process more manageable with its robust Measure editor and measurement labels.
Using the Measure editor, you can interactively generate and save measurements directly in your molecular structure. Here’s a step-by-step guide to streamline your workflow when working with measurement labels:
Getting Started with Measuring
The Measure editor is easily accessible from the left-side menu in the viewport (
) or via the shortcut Ctrl/Cmd + M. This tool allows you to:
- Click on a bond to toggle its length measurement.
- Click on two atoms to measure the distance between them.
- Click on three atoms to calculate angles.
- Click on four atoms to measure torsion angles.
While these measurements are temporary by default, they don’t have to disappear. By pressing Enter, you can save them as labels, embedding them directly in the document for future reference.
Enhance Workflow with Saved Labels
Saved measurement labels open a range of possibilities. They remain visible even when navigating your structure at different zoom levels. Additionally, these labels are tied to their associated atoms, so measurements are automatically updated if the structure changes—whether you’re editing or moving atoms within the molecule.
Labels can also be inspected for additional details using SAMSON’s Inspector. For example, a saved atom-atom distance label provides extra measurements, like projections on planes.
Customizing Labels
To tailor labels to your needs, SAMSON gives you complete control over their appearance. You can:
- Change text font, size, and color, as well as the color of distance lines and angle planes.
- Reset colors to default by double-clicking the text in the Inspector or using the clear button (
). - Specify all label preferences, including the default font for unspecific labels, via Preferences at Preferences > Rendering > Labels.
Why Save Measurements as Labels?
By saving your measurements, you gain more than just persistent data. Your saved labels will be stored when saving documents in SAMSON’s file formats (.sam or .samx). This ensures your work remains consistent, even across sessions. Moreover, these labels assist in documenting your modeling process, making collaboration or revisiting past projects more effective.
Conclusion
For molecular modelers, managing measurements efficiently can make all the difference in structure analysis. The Measure editor and its label-saving functionality in SAMSON offer a comprehensive solution: precise, customizable, and adaptable measurements integrated directly into your workflow. To ensure you get the most out of your models, we highly recommend exploring this feature further.
