Mastering Attribute Filtering with the Inspector Tool in SAMSON

When working on molecular modeling tasks, examining and editing the properties of molecular nodes is an essential part of the workflow. However, as the complexity of your system grows, so does the number of visible attributes for each selected node. This can make it challenging to find and focus on the exact properties you want to modify. Fortunately, SAMSON’s Inspector tool includes a powerful filtering feature that makes this process seamless and efficient.

Why Attribute Filtering Matters

If you’re modeling complex molecular structures, there’s a good chance you’ve experienced the frustration of trying to sift through long lists of attributes to locate a single one, such as the position of an atom or a specific molecular property. The ability to quickly filter and pinpoint the attributes you’re interested in can save substantial time and effort, especially during iterative workflows involving multiple refinements and adjustments.

How to Use Filtering in the Inspector

Filtering attributes in the Inspector is straightforward, but it can make a big difference in your efficiency. Here’s how it works:

  1. Select your nodes: Start by selecting one or more nodes in your molecular system. For example, you can select individual atoms, residues, or any other entity supported by SAMSON. If you’re unfamiliar with the selection process, refer to the Selecting guide.
  2. Open the Inspector: You can access the Inspector via the interface menu (Interface > Inspector), by using the shortcut (Ctrl + 2 on Windows/Linux or Cmd + 2 on Mac), or through the context toolbar.
  3. Type in a keyword: In the Inspector’s filter box, type the name or keyword related to the attribute you’re looking for. For instance, if you’re interested in the position attribute of an atom, simply start typing “position.”
  4. Interact with the results: The Inspector will instantly narrow down the visible list of attributes to those that match your filter. This makes it easy to find, modify, or observe specific properties without needing to scroll through irrelevant information.

An Example: Modifying Atomic Position

Let’s put filtering into action. Suppose you’ve selected an atom and want to adjust its position. Here’s what happens:

  • Type position in the filter box. The Inspector will display only the position attribute, hiding all others from view.
  • Modify the position value. For example, change its coordinates by inputting new values. You’ll observe the atom moving in real time as its position updates.

For a visual guide, refer to the image below, which demonstrates filtering and modifying an atom’s position:

Advantages of Filtering in Large Molecular Systems

Attribute filtering isn’t just a convenience—it’s a necessity in large molecular systems. Whether you’re altering bond lengths, examining atomic properties, or adjusting group-level attributes, filtering ensures you focus on what matters most without distractions. Additionally, when working with multiple selected nodes, changes to attributes, like position, can be applied to all selected nodes at once, further enhancing productivity.
