Measuring precise molecular distances, angles, or dihedrals is critical for molecular modelers, but visualizing and preserving these data can often be time-consuming. This is where SAMSON’s Measure editor and its ability to save measurements as reusable labels makes the task efficient and straightforward.
Why Save Measurements as Labels?
Imagine you’re analyzing a complex molecule in detail. You measure atom-to-atom distances, bond lengths, angles, and torsions, but these temporary measurements disappear as soon as you make the next one. Not only does this disrupt your workflow, but you may lose valuable insights. With SAMSON, you can avoid this issue by saving measurements as labels directly in your document. Labels allow you to:
- Preserve measurements for future reference.
- View data persistently, even when zooming in or out.
- Access additional information, such as projections of atom-to-atom distances on planes, saved in the Inspector.
How to Add Measurement Labels
Follow these simple steps to create and save measurement labels for distances, angles, and more:
- Use the Measure editor (
or Ctrl/Cmd + M) to measure any distance, angle, or torsion. - Display the measurement you need by selecting the relevant atoms or bonds:
- Click on a bond to display its length.
- Click on two atoms to display the distance between them.
- Click on three atoms to display their angle.
- Click on four atoms to display their torsion.
- Press Enter to save the displayed measurement as a label.
Saving the label ensures that it stays visible and accessible for further use. Even better, labels saved in SAMSON documents are retained when you save files in .sam or .samx formats.
Bring Labels to Life: Customizations
Measurement labels are not just static data points; they can be tailored to suit your work environment, providing clarity and organization. Here’s how:
- Visibility: Labels adjust visibility depending on zoom levels, making large molecules easier to manage.
- Customization: Control label appearance completely, including font size, text color, distance line color, and angle plane color via the Inspector.
- Reset functionality: Easily reset colors and text to default settings when needed—just double-click on the settings in the Inspector.
Customizing labels not only enhances the visual clarity of your work but also makes it easier to share data with collaborators.
Save Time, Reduce Errors
Accurate measurement and visualization are vital for informed decision-making in molecular modeling. By saving measurements as labels in SAMSON, you ensure that no critical data point is lost in the process. Additionally, these labels update automatically when the associated atoms are moved or modified, ensuring that your data stays accurate and reliable during simulations or structural changes. Whether you’re modeling complex biomolecules or optimizing chemical structures, this feature streamlines your process.
