A molecular structure can contain exactly the information you need—and still be difficult to read. Atoms, chains, ligands, water molecules, and multiple representations can compete for attention in the viewport. The goal is not simply to make the structure look polished: it is to make the important parts easy to distinguish, inspect, and communicate.
This workflow uses SAMSON’s visual models and visibility controls to build a clearer view without changing the underlying molecular structure. It is especially useful when you want to emphasize a protein’s shape while keeping a ligand or selected residues visible.
Start with the scope of the view
Before adding a representation, decide what it should apply to. In SAMSON, a new visual model is applied to the current selection—or to the whole document if nothing is selected. That behavior can save time, but it can also create an unexpectedly busy view if a selection is left active.
For a targeted representation, select the intended molecule, chain, or other nodes first. If you want the model applied throughout the document, clear the selection. You can add a visual model from Visualization > Visual model, or use Ctrl/Cmd + Shift + V, then choose a model such as Ribbons for secondary structure.
One practical combination is to use Ribbons to show the protein’s overall fold and Licorice to show selected atoms or a ligand in more detail. Since visual models can be added to the same nodes, you can layer representations rather than forcing one model to do everything.
Reduce visual competition with visibility controls
Once the key representations are in place, hide anything that distracts from the point you want the viewer to see. In the Document view, uncheck a node to hide it from the viewport; check it again to show it. This works for structural nodes such as chains and residues, as well as visual models and other supported nodes.
Visibility follows the node hierarchy: hiding a parent hides its descendants. A useful detail is that a parent’s checkbox can still appear ticked when at least one descendant remains visible. So if a chain or residue seems partly visible, inspect its children rather than assuming the visibility setting has failed.
You can also select nodes in the Document view or viewport and use the Visibility section of the context toolbar to show or hide the selection. For example, when you add Ribbons to a protein, hiding the structural model can remove the default atom-and-bond display while leaving the Ribbons representation visible. This avoids the visual clutter of showing both representations when you only need the secondary structure.
Use transparency to keep context
Hiding is not always the best choice. Sometimes a faint structural model provides useful context behind a more prominent visual representation. For supported nodes—including structural models, folders, labels, many visual models, and meshes—you can select the node and adjust transparency in the Inspector.
This gives you a simple visual hierarchy: keep the feature of interest easy to see, and make surrounding structure less dominant. If a node does not expose a transparency parameter, use visibility or a different visual model instead; transparency is available only for some node types.
Check the view before capturing it
Before saving an image, orient the molecule in the viewport and check that the important features remain visible at the intended framing. You can take a viewport capture with F10; use Ctrl/Cmd + F10 to choose where to save it, or Shift + F10 to copy it to the clipboard. Capture preferences are available under Interface > Preferences > Interface > Captures.
For a quick starting point, a visual preset can apply multiple representations and color schemes together. Presets are useful when you want a consistent initial view; you can then refine the selection, visibility, or transparency for the specific structure and message.
A clear molecular view is often the result of a few deliberate choices: apply representations to the right nodes, hide redundant displays, and preserve only the context that helps interpretation. For additional workflows and examples, see the SAMSON visualization guide.
