For molecular modelers, the excitement of exploring a powerful integrative molecular design platform like SAMSON can sometimes be dampened by installation challenges. This post focuses on addressing some key pain points encountered during the installation process, ensuring a smoother start to using SAMSON.
Graphics Issues: Intel-Specific Warnings
If you’re installing SAMSON and using an Intel graphics card, you might encounter a warning during the installation process. While this might raise concerns, here’s what you need to know:
- The warning is particularly relevant if Intel is your only graphics provider.
- If you also have an NVIDIA or AMD graphics card, you can safely ignore the warning and proceed with installation.
The installer ensures that users are informed about potential performance issues. If you’re unsure about your graphics setup, we recommend consulting your system specifications before continuing.
Network Proxy Configuration
Many installations fail due to proxy settings, especially in corporate or regulated environments. SAMSON’s installer allows you to test network connections and configure a proxy if your network requires one.
Here’s how you can handle this:
- Click the Test Connection button during the setup to validate the installer’s ability to reach SAMSON Connect.
- If the test fails, review and enter your proxy settings. You may need to request this information from your system administrator.
- After entering the proxy parameters, re-test the connection to ensure the installer can proceed.
The connectivity check is crucial since SAMSON retrieves the software and extensions directly from SAMSON Connect during installation.
Linux Configurations
Linux users often face additional steps during setup. If you’re using a Linux OS, you’ll likely need to make the installer executable and run it using the following commands:
|
1 2 3 4 |
cd ~/Downloads chmod +x ./SAMSON-Setup.run QT_QPA_PLATFORM=xcb ./SAMSON-Setup.run |
These commands ensure the installer can execute properly. If OpenGL or dependency issues arise, refer to the Troubleshooting page for further guidance.
Advanced Installation Options
For users with specific needs, such as choosing a custom installation path or reverting to an older SAMSON version, the Advanced Mode offers flexibility:
- Enable Advanced Mode directly in the installer.
- Select your preferred installation path to organize files according to your system’s structure.
- Choose an earlier version of SAMSON, especially if extensions or workflows you rely on are optimized for a prior release.
This mode is particularly valuable for those integrating SAMSON into customized environments or legacy workflows.
Additional Resources
If challenges persist, head to the Troubleshooting section of the documentation. Regularly updating SAMSON when a new version is available can also avoid issues, as the platform and extensions are designed to coordinate seamlessly with the latest releases. Updates can be triggered manually via Interface Menu > Update SAMSON.
