When working on complex molecular modeling projects, researchers often need specific tools tailored to their workflows. One common challenge? Quickly finding and managing the right computational modules without interrupting your progress. That’s why flexible software like SAMSON—with customizable add-ons called SAMSON Extensions—can make a difference. But how exactly can you add, try, subscribe to, or remove these modules?
This post walks you through the key steps to help you build and reorganize your ideal modeling environment using the SAMSON Connect marketplace. Whether you’re exploring free modules or managing trial subscriptions, this guide is designed to keep your research moving with minimal friction.
Browse and Add New Extensions
Visit the SAMSON Marketplace to view all available SAMSON Extensions. These range from visualization helpers to simulation engines. Modules are listed with a description, platform compatibility, and version information.

For publicly available and free extensions, simply sign in and click Add. The extension is marked as “Added,” and SAMSON will automatically install it after restart.

Try Before You Subscribe
Some extensions are available via a subscription. If you’re unsure whether a module suits your work, click Request trial. No credit card is needed, and an extension in a trial period will show up as “Trying”.

Subscribing to Paid Extensions
When you’re ready to commit, hit Subscribe to pick a monthly or yearly plan. Academic users also have access to specialized pricing.

Removing Extensions
To clean up your installation or streamline your toolkit, pick any previously added module and hover your mouse over the Added button—it turns into Remove. One click, restart SAMSON, and it’s gone.

Manage Your Subscriptions
To view or update your current subscriptions, head to Account > Settings > View my subscriptions. Here you can stop trials, manage paid plans, or revisit previous tools you’ve used.

Removed extensions remain visible in your account for easy reactivation in future projects. This way, you don’t lose valuable configurations if your needs change.
Final Thoughts
Building a flexible computational environment doesn’t need to be disruptive. Whether you’re exploring new science tools or tailoring your workspace, SAMSON Extensions make it easy to adapt. For researchers who want full control over their molecular modeling toolkit, knowing how to manage these add-ons can lead to more productive workflows.
