Molecular modeling can be a highly complex task, especially when dealing with intricate systems like large biomolecules. Navigating between different regions of interest, applying specific transformations, or comparing structural elements often adds to this complexity. To address this, SAMSON introduces Quick Groups, a tool designed to reduce friction in your workflows and enhance productivity.
What are Quick Groups?
Quick Groups are temporary selections that can be rapidly created, accessed, and modified. They allow you to save specific selections in a SAMSON document and retrieve them instantly, making them especially valuable for tasks like:
- Highlighting and navigating structural elements of interest (e.g., ligands, residues).
- Designing and analyzing complex molecular models.
- Comparing specific regions of a molecule.
- Streamlining workflows by focusing on areas where specific operations or visualizations are applied.
With Quick Groups, you can manage up to 10 groups per project, making it easy to toggle between selections and perform complex operations without losing track of your progress.
Key Benefits of Quick Groups
Quick Groups provide molecular modelers with the following advantages:
- Improved organization: Keep regions of interest defined and accessible.
- Faster workflow: Instantly return to and manipulate groups with keyboard shortcuts.
- Greater flexibility: Easily redefine or clear Quick Groups to suit evolving projects.
- Precise visualization: Compare sections of the model or focus on particular elements with ease.
How to Assign Quick Groups
Assigning Quick Groups is straightforward. After making your selection (e.g., atoms, residues, or molecules), you have two convenient methods to save it:
- Hover and Assign: Hover over a Quick Group slot in the Document view and press Shift + click.
- Keyboard Shortcut: Press Shift + number (e.g., Shift + 2) to assign your selection to Quick Group
2.
Once saved, these groups appear in the lower section of the Document view, allowing you to recall and interact with them quickly.
Switching Between Quick Groups
Switching between groups is just as seamless. Here are your options:
- Use keyboard shortcuts: Press numbers (1, 2, etc.) to select the corresponding Quick Group.
- Directly click: Select Quick Groups from the icons in the Document view.
- Double press the number key (e.g., 11) to zoom into your selection for a closer view.
This mechanism resembles control groups in real-time strategy games and is incredibly intuitive, streamlining navigation in SAMSON.
Illustrative Example: A Workflow with Quick Groups
Here’s a practical use case to show how Quick Groups simplify molecular design:
- Select the ligand in your model and assign it to Quick Group 1.
- Select the receptor and assign it to Quick Group 2.
- Select water molecules and assign them to Quick Group 3.
- Navigate between these groups using 1, 2, and 3 to analyze interactions or apply specific visualizations to these distinct regions.
This example not only demonstrates Quick Groups’ speed but also highlights their potential for improving focus and efficiency.
