When exploring ligand unbinding pathways during molecular modeling projects, it’s crucial to have tools that efficiently export and visualize results. Understanding how to manage your pathway results in SAMSON’s Ligand Path Finder app can help molecular modelers turn raw calculations into actionable insights.
Why Exporting and Visualizing Pathways Matters
For many researchers, analyzing ligand unbinding pathways goes beyond finding a feasible path. Refining and visualizing energy profiles, comparing various results, and exporting specific data points or trajectories are essential for gaining deeper insights into molecular interactions. This process ensures that every aspect of the path—energies, transition states, and spatial movements—is clear and usable for reporting or further simulation.
Exporting Path Results in SAMSON
The Ligand Path Finder app offers versatile options for exporting path results once you’ve computed unbinding pathways. Here’s what you can do:
- Copy path table content: Select the desired paths from the result table, right-click, and choose Copy table content. You can also press Ctrl + C (or Cmd + C on Mac). This allows you to copy the entire content for documentation or analysis purposes.
- Copy path energy: To focus on the energy values of specific paths, use the right-click option Copy path energy. This is ideal for plotting or further energy analysis outside SAMSON.
- Export paths: Convert selected paths into your SAMSON document as trajectories. Use the Export paths button to do so. This makes paths accessible as trajectories for visualization within the SAMSON environment.
- Export conformations: Want to save specific states along a pathway? Select paths, choose an interval for the export, and click Export. This creates a detailed output of conformations, enabling deeper investigations.

Visualizing Energy Curves and Conformations
Once paths are calculated, the results tab in the app lets you interactively visualize energy profiles and explore conformations:
- Energy curves: Select a path or multiple paths in the result table to plot their energy curves. This allows a direct comparison of energy profiles across pathways.
- View conformations: When a path is selected, use the slider to navigate through its conformations. The app reflects your selection in the SAMSON structural model, showing the ligand’s spatial position and corresponding energy in the Universal Force Field window.
Below is how SAMSON showcases results with energy pathways and conformational states:
Export with Precision for Further Analysis
Pathways can also be exported in .sam or .samx formats for external usage. If you only require trajectories for specific atoms, the Export Along Paths app provides highly customizable export options. For more details, you can refer to the separate Export Along Paths tutorial.
Conclusion
Efficiently exporting and visualizing ligand pathway data is integral to interpreting molecular interactions. With SAMSON’s Ligand Path Finder, molecular modelers have robust features to make the most of their trajectory data. You can now confidently export, refine, and analyze your unbinding pathways for comprehensive insights.
