The First 10 Minutes with SAMSON: A Calm Route from Install to First Structure

A molecular modeling session can get stuck before it begins: the application is installed, but it is unclear whether the computer meets the requirements, how to launch the program, or what to do after the first window appears. A simple sequence helps keep these questions separate. Check compatibility, install and launch SAMSON, then choose one clear next step.

SAMSON is a platform for computational nanoscience, with applications across life science, materials science, physics, electronics, chemistry, and education. Its open architecture can be extended with tools for tasks such as building models, running calculations, and visualizing results. That flexibility is useful, but it also means new users do not need to explore everything at once.

Before opening the application

First, check Requirements and platforms. This is the place to confirm operating-system support, hardware expectations, and Linux dependencies. Doing this before troubleshooting a failed launch can help distinguish a setup issue from a problem with a specific structure or workflow.

Then follow Install SAMSON for the installer process, including sign-in and key entry. If installation or graphics setup does not behave as expected, use the Troubleshooting guide rather than repeatedly changing unrelated settings.

Find the right launch route

• Windows: Look for SAMSON in the Start menu; searching for its name may take you there. The documentation also gives an executable path, but its example includes a specific version folder. If that path does not match your installation, use the installer location for your own setup.
• Mac: Open SAMSON from Launchpad or the Applications folder. The documented application folder is $HOME/Applications/SAMSON.app/.
• Linux: You can use the Apps dashboard or run ./SAMSON-Core.sh from the SAMSON Binaries folder. If you want a shorter terminal command, the documentation shows how to create a samson alias in ~/.bashrc or ~/.zprofile. After adding it, open a new terminal and run samson. For AMD/ATI graphics issues, see the Linux section of Troubleshooting.

The Getting Started page lists SAMSON 2026 R1 as the current version. Its example Windows and Linux paths contain a 11.0.0 directory, so treat those paths as examples to compare with your installation, not as a reason to rename folders or assume your version is different.

Choose one useful next step

Once SAMSON opens, resist the urge to learn every tool immediately. If you want to understand the layout, start with First look: the interface. If your immediate goal is to inspect a molecule, go to Loading molecules. For a broader, compact introduction to navigation, documents, visualizations, and simulations, use the Quick Start Guide.

SAMSON downloads a set of default Extensions the first time it starts. You can leave extension choices for later; when you are ready to customize your setup, sign in and browse the Marketplace. Extensions include different kinds of tools, so choosing them around a specific task is a more manageable starting point than browsing without a goal. For a short introduction to the interface, the webinars page also collects onboarding and release recordings.

The practical sequence is simple: verify requirements, install, launch using the route for your operating system, then follow the guide that matches what you want to do next. For the complete onboarding details, visit Getting Started.
