Handling diverse file formats effectively is one of the most significant challenges faced by molecular modelers. Whether you’re working with molecular structures, trajectories, 3D geometries, or scripts, data compatibility can either accelerate or hinder your workflow. This is where SAMSON, the integrative molecular design platform, excels by offering extensive support for a wide array of file formats. In this blog post, we’ll dive into how SAMSON simplifies molecular modeling through its ability to seamlessly import, export, and even embed various file types.
What makes SAMSON versatile?
SAMSON supports both proprietary and third-party file formats, tailored to meet the vast needs of molecular modelers. From importing detailed molecular systems to exporting 3D geometries, SAMSON serves as a powerful hub for managing molecular data. Let’s explore some of these formats more closely:
SAMSON’s native formats: SAM and SAMX
SAMSON uses two native file formats—SAM (binary) and SAMX (XML)—to store molecular systems, notes, simulators, animations, and even entire folders. These formats can also embed external files like scripts, data, or images, ensuring nothing critical is lost when moving projects between systems. This flexibility enhances collaboration and project scalability.
Molecular structures and beyond
One of the standout features of SAMSON is its support for numerous molecular structure formats, including:
- PDB: The standard format for protein structure data, with aliases like ENT and VDB.
- CIF: Ideal for crystallographic information, used via tools like the Crystal Creator App.
- GRO: GROMACS structure files for biomolecular simulations.
- MMTF: Efficient and compact macromolecular transmission format files.
Formats like XYZ, MOL2, and SDF are also fully supported, enabling interoperability with other scientific tools.
Trajectory data: Visualize motion with ease
For modelers working with molecular dynamics, properly handling trajectory data is crucial. SAMSON supports popular trajectory formats, such as DCD, NC (NetCDF from AMBER), and XYZ. Extensions like the GROMACS Wizard allow you to generate GROMACS-compatible files, further improving your ability to visualize molecular motion.
3D geometries and visual models
Molecular systems often come with complex 3D shapes and geometries. SAMSON allows users to work with Wavefront OBJ and glTF files for 3D visualization. This capability extends to exporting visual models and animations.
Automation with Python scripting
In addition to these diverse file format supports, SAMSON’s integration with Python scripting stands out. It allows users to open, edit, and execute Python .py files directly within the platform, using the built-in Code Editor. This functionality can dramatically improve workflow efficiency.
Extending format compatibility
If SAMSON doesn’t natively support a specific file format you need, there’s no need to worry. You can develop your own importers and exporters using the Extension Generator. Alternatively, you can contact the SAMSON team via the SAMSON Connect Forum to request new formats.
