For molecular modelers, identifying and modifying properties at an atomic or structural level is a routine yet essential task. However, this seemingly simple process can quickly become a bottleneck without the right tools. SAMSON’s Inspector offers an efficient solution to this challenge by providing a clear, intuitive interface to inspect and edit node attributes. Whether you are analyzing a single atom or a group of complex molecular structures, the Inspector facilitates easy and powerful property management.
What Does the Inspector Do?
The Inspector allows you to view and modify properties (attributes) of selected nodes in your molecular model. Nodes can include atoms, bonds, residues, or other molecular elements. By simply selecting a node and opening the Inspector, you can immediately access these attributes, grouped neatly by node type and attribute category.
The process is flexible: even when working with multiple selected nodes, the Inspector is tailored to manage attributes responsibly, including simultaneous adjustments across the selection. With the added ability to reset certain attributes to their default values, the Inspector significantly simplifies repetitive tasks.
Opening the Inspector
You can open the Inspector through various means:
- Interface menu: Navigate to Interface > Inspector.
- Keyboard shortcuts:
- Ctrl + 2 for Windows/Linux.
- Cmd + 2 for macOS.
- Context toolbar: Use the context toolbar visible when selecting nodes.
Digging into Attributes
Once you’ve selected a node or a group of nodes, you can explore and adjust their properties through the Inspector. Attributes of the selected node type(s) (e.g., Atom, Bond, Residue) are grouped logically, making it easy to navigate. For instance, when selecting an atom, you can modify attributes like its element type, which automatically updates dependent data, such as atomic weight or symbol. However, intrinsic properties such as atomic weight cannot be directly edited, as they are derived from the element type itself.
Below is an example of inspecting a group of nodes (a residue with its descendants):

If you hover over certain attributes, you may notice that the cursor changes, enabling you to reset those attributes to their default values. This is especially helpful for resetting modified parameters without manually recalibrating each element:

Efficient Multi-node Modifications
The Inspector scales gracefully to accommodate larger selections. For instance, selecting multiple atoms allows you to modify their attributes collectively. Coordinate adjustments ensure that the selected atoms shift position coherently. To maintain their relative arrangement, a Relative option is available, which can be toggled off for uniform attribute values:


Filtering Attributes Made Easy
If you’re dealing with a node that has an extensive set of attributes, the Inspector’s filtering feature eases navigation. By typing a keyword such as position into the search bar, the Inspector narrows down the visible attributes to those matching your query. This saves time and enhances precision when accessing specific properties:

Once filtered, you can directly modify the visible attributes as needed and immediately observe the results in your molecular model:

Conclusion
The Inspector in SAMSON offers an indispensable resource for molecular modelers. It bridges the gap between detailed attribute management and usability, ensuring that property adjustments are efficient and intuitive, whether you focus on individual nodes or groups. By leveraging its functionalities, you can enhance your productivity without compromising on precision.
