A molecular modeling workflow can depend on more than the core application. You may need a particular extension for a task, but choosing one raises practical questions: Is it available for your operating system? Does it support your SAMSON version? Is it included in your plan, free to add, or offered by subscription? And once you have tried it, how do you remove it?
SAMSON Connect’s Marketplace brings these decisions together. A little preparation before adding an extension can save time and make it easier to keep your installation aligned with the work you actually do.
Start with the extension’s details
Browse the Marketplace to see the available SAMSON Extensions. Open an extension’s page before adding it: its description, authors, supported operating systems, extension versions, and compatible SAMSON versions are listed there. Check these details against your setup and the task you have in mind.
This simple check is useful when you are comparing tools or following a workflow that names a specific extension. Rather than selecting by title alone, confirm that the extension is available for your operating system and for the SAMSON version you use.
Understand how access works
Extensions can be included with your current plan, freely available to add, or accessible through a subscription. The available functionality in SAMSON can vary by plan. SAMSON always has a Free (Starter) plan, though some functionality and the number of free extensions may be limited.
If an extension is free to add, sign in to SAMSON Connect and select Add on its page. The extension will be marked as Added. After you restart SAMSON, it downloads and installs the extension automatically.
For an extension offered through a subscription, you can request a trial or subscribe. The documentation says that requesting a trial does not require credit card information. If you decide to subscribe, choose the monthly or yearly option; an academic plan is available if you have academic status.
Keep your installation manageable
It is easy to accumulate tools while exploring what is available. A useful habit is to add an extension when you have a clear use for it, then revisit your list when your project needs change. Your account settings include View my extensions and View my subscriptions, making it possible to review what you have added and what you are paying for.
To remove a free extension, sign in and find it through the Marketplace or through Account > Settings > View my extensions. Open the extension’s page, hover over the Added button until it changes to Remove, and select it. To manage subscriptions, go to Account > Settings > View my subscriptions. After SAMSON is restarted, a removed extension is removed from the installation. The extension remains listed in your account settings, so you can add it again later if you wish.
In practice, the key is to treat extension management as part of setting up a modeling workflow: check compatibility, understand the access option, and know where to review or remove the tool afterward. That makes it easier to explore specialized capabilities without losing track of what your installation contains.
