What's new in SAMSON 2025 R3

We are pleased to announce that SAMSON 2025 R3 is out.

What’s new

This is a small release, as the upcoming data science features are still in development, but it has several quality-of-life improvements, including:

• Extended NSL: the Node Specification Language has more attribute spaces and attributes, to facilitate further advanced selections. You can learn more about this in the corresponding documentation page (and SAMSON AI can convert your natural language queries into NSL expressions 😉 : just use the /nsl command, or even the /select command to directly select whatever is matched by the NSL expression).
• Improved Gaussian surfaces: the surface topology has been improved when ligands are covalently bound to proteins.
• Clickable tooltips: all links contained in tooltips are now clickable when the tooltips appear while hovering a command (before, the links were only clickable when the tooltips were shown as results of Find everything). We also added a shortcut to ask SAMSON AI in each tooltip:

Clicking the tooltip automatically asks SAMSON AI for a description (in case the one in the tooltip is not sufficient), tips and examples:

For developers

This release does not have major changes in SAMSON API - the changes are mainly internal improvements. See the Developer Guide: Changelog.
