For molecular modelers, the seamless loading and management of molecular structures can save significant time and effort. SAMSON makes this process intuitive and flexible, and in this post, we will explore the essentials of loading molecules within the SAMSON platform, discussing useful tips and steps for both beginners and experienced users.
Loading Molecules: The Basics
To load a molecular file, SAMSON offers multiple straightforward options:
- Navigate to Home > File > Open and choose your file.
- Use the keyboard shortcut
Ctrl + Oon Windows/Linux orCmd + Oon Mac for quick access (Ostands for Open).
If you want to revisit a previously accessed file, head over to Home > File > Recent, where you’ll find your most recent files listed for convenience.
How SAMSON Handles File Formats
File compatibility is a major concern for molecular modelers. Thankfully, SAMSON uses specialized importers to load files based on their specific formats. By default, SAMSON supports a wide range of molecular file formats such as PDB, CIF, MMTF, and many more. You can review the full list of supported formats.
If you need additional importers to load less common files, take advantage of the Marketplace on SAMSON Connect. It offers a variety of extensions to enhance your SAMSON experience. To learn how to add extensions, visit the Extensions section in the documentation.
Fine-Tuning Import Parameters
In some cases, specific files and their respective formats might require additional parameters to be configured. For example, importing a PDB file may involve user-defined preferences displayed in a dialog box. Here’s a screenshot of a sample import dialog for reference:
Customized parameters are saved for efficient reuse, ensuring a smoother workflow in future projects. Once the necessary adjustments are made, press OK or Enter to load your file into SAMSON. The molecular structures will then appear in the Document view and the viewport.
Need More Molecules? Try Fetch Structures
If you’re looking for public molecular databases to download specific files, SAMSON includes a convenient tool called Fetch Structures. Navigate to Home > Fetch and use it to download molecular structures from the RCSB Protein Data Bank. Accepted formats include PDB, mmCIF/PDBx, and MMTF. This feature is ideal for accessing high-quality molecular datasets without leaving the platform.
Conclusion
SAMSON’s streamlined molecule-loading capabilities make it a valuable tool for molecular modelers. Whether you’re opening files, configuring specific import parameters, or fetching structures from databases, these features are designed to optimize your workflow and save time.
