For molecular modelers using SAMSON, expanding the platform’s functionality with extensions can be transformative. Extensions allow you to tailor SAMSON to your specific needs, unlocking tools for visualization, simulation, analysis, and more. But navigating the process of adding, managing, or even trying these extensions can sometimes feel daunting. Here’s a practical guide to simplify this process.
Understanding the Extensions Marketplace
The SAMSON Extensions Marketplace is a central hub where you can explore modules that enhance SAMSON. From here, you can find all published extensions organized by purpose and utility. Whether you’re looking for freely available add-ons or ones that require a subscription, the Marketplace is the starting point for managing your extensions effectively.

Adding Free Extensions
Many extensions in the Marketplace are free to use. Once logged into your SAMSON Connect account:
- Navigate to the Marketplace.
- Find an extension that suits your needs and click the Add button.
A selected extension will be marked as “Added,” signaling that it has been linked to your SAMSON installation. Upon restarting SAMSON, the software automatically downloads and installs the extension for immediate use.


Trying Subscription-Based Extensions
Some extensions require a subscription but often allow a trial period. To try an extension:
- Click the Request trial button in the extension’s page.
- No credit card information is required for trying an extension.
During the trial period, the extension will display as “Trying.” Once the trial period ends, you can opt to subscribe to additional plans based on your requirements.


Subscribing for Advanced Features
Interested in unlocking premium tools? Subscription-based extensions offer monthly or yearly payment options that cater to both academic and non-academic users. Academic users often have access to specific academic plans that make these tools more accessible. After subscribing, the extension will be marked as “Subscribed,” ensuring you can take full advantage of it.


Managing Existing Extensions
Need to remove or deactivate an extension? SAMSON makes it straightforward:
- Go to your account settings on SAMSON Connect and click View my extensions.
- Select an extension you wish to remove. Hover over its “Added” button—it will change to “Remove.” Click to confirm removal.

If you change your mind, previously removed extensions will still appear in your account’s extension overview for easy future reinstallation.
Subscriptions Overview
Managing subscriptions is just as convenient. By navigating to Account > Settings > View my subscriptions, you can oversee ongoing subscriptions, cancel plans, or adjust them to fit changing needs. This page gives you a clear breakdown of all your active commitments, simplifying their management.


Conclusion
Optimizing SAMSON with the right extensions can enhance your modeling workflow significantly. By familiarizing yourself with the Extensions Marketplace and developing a good strategy for managing your tools—be they free or subscription-based—you’ll unlock SAMSON’s full potential.
