A molecular structure can be scientifically rich and visually overwhelming at the same time. When atoms, bonds, chains, ligands, and waters all compete for attention, it becomes difficult to show the feature you actually want someone to notice. The solution is often not a more elaborate render: it is a deliberate sequence of choices about representation, visibility, and framing.
This workflow in SAMSON helps turn a crowded structure into a clearer view while keeping the underlying model available. It is useful when preparing a figure, explaining a binding site, or simply trying to inspect a complex system.
Start with the question your image should answer
Before changing the display, decide what the viewer should notice. Is the focus a protein fold, a ligand, a group of chains, or a few atoms? That choice guides which parts should use a prominent visual model and which parts can be hidden or shown more subtly. If you need to work with particular atoms, residues, or chains, select them first; visual models are applied to the current selection, or to the whole document when nothing is selected.
Choose a representation that separates features
Visual models provide alternate representations of structural models. For example, a Ribbons (secondary structure) model can emphasize the protein’s overall fold, while a Licorice model can make atoms and bonds easier to inspect in a smaller region. Add a visual model from Visualization > Visual model, or use Ctrl/Cmd + Shift + V, then choose the model type.
One practical approach is to use a broad representation for the structure and a more detailed one for the feature of interest. You can apply multiple visual models to the same nodes. If the original atom-and-bond representation adds visual noise, hide the structural model in the Document view while leaving the added visual model visible.
Check the selection before adding anything
This small check prevents a common source of confusion: a new visual model may appear on more of the structure than intended. Before adding it, confirm that the intended nodes are selected—and that unrelated nodes are not. If you want the model applied to the entire document, clear the selection first. The Document view is useful for selecting chains and checking which models belong to which parts of the structure.
Reduce clutter with visibility, not deletion
Hiding nodes lets you simplify the viewport without removing them from the document. In the Document view, uncheck a node’s box to hide it and check it again to show it. Hiding a parent node also hides its descendants by default, so hiding a residue, for example, hides its atoms. A parent can still appear checked when some of its descendants remain visible.
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. This makes it practical to isolate chains or other groups while keeping the rest of the model available to restore later.
Use color and transparency to establish hierarchy
Color can help distinguish a visual model or structural group from its surroundings. Select the model and apply a color scheme from Visualization > Color, its context toolbar, or the Inspector. For detailed options such as color schemes and palettes, see the Colorizing guide.
For supported nodes—including structural models, folders, labels, meshes, and many visual models—you can adjust transparency in the Inspector. A semi-transparent structural model can remain as context behind an opaque representation, instead of either obscuring the important feature or disappearing completely. Select the relevant node before changing its transparency.
Frame and capture the result
Once the representation is clear, orient the molecule in the viewport. When you are ready to save the view, press F10 to capture it to the folder set in capture preferences. Use Ctrl/Cmd + F10 to choose where to save the capture, or Shift + F10 to copy it to the clipboard. These options make it easy to compare a working view with a saved figure without changing the molecular structure.
A useful order to remember is: select the right nodes, apply the representation, hide distracting elements, then color or adjust transparency to make the visual hierarchy clear. If the goal is a reusable setup, consider a visual preset; if you need finer control of effects or final-quality output, use the specialized rendering guides.
