As a molecular modeler, your workflow often depends on integrating the right tools at the right time. SAMSON helps streamline activity through its modular approach using SAMSON Extensions. Learning how to add, try, subscribe to, or remove these extensions can help you stay focused on your research while keeping the software lean and customized for your needs. This guide gives a clear overview of how to manage extensions in SAMSON through SAMSON Connect.
Finding Extensions That Fit Your Needs
On the Marketplace section of SAMSON Connect, you’ll find a diverse selection of extensions—ranging from simulation wizards to visualization tools. Each extension has a dedicated page with its description, compatibility details, supported versions, and authorship.

How to Add Free Extensions
If a SAMSON Extension is freely available, and you are signed in, a simple click on the Add button will attach it to your current installation of SAMSON.

Once added, the status will change to “Added”, and the extension will be downloaded when you restart SAMSON.

Removing Extensions You No Longer Use
To remove a free extension, go to your account on SAMSON Connect, then click View my extensions. Hover over the Added button for the extension you wish to remove; it will change to Remove.

For subscribed extensions, go to Account > Settings > View my subscriptions to manage your subscriptions. After restarting SAMSON, the extension will no longer be part of your setup.

Interestingly, even after removal, extensions remain visible on your account. This allows easy reinstallation if you decide to add them again later.
Manage Smarter, Model Better
Whether you need quick visualization tweaks or advanced simulation modules, SAMSON’s extension management makes it possible to adapt the platform to your changing modeling needs. Customization and control, right at your fingertips.
