For molecular modelers, visualization is the gateway to insights. But when working with complex molecular systems, setting up visuals can often feel overwhelming and time-consuming. What if there was a way to instantly apply structured and aesthetically pleasing representations to your molecular structures? Enter Visual Presets in SAMSON, an efficient way to streamline visual representation.
Visual Presets in SAMSON allow users to apply multiple representations and color schemes to molecular systems with just a few clicks. This feature is perfect for presenting your molecular models clearly and effectively, whether you’re analyzing intricate protein-ligand interactions, preparing an illustrative image for a publication, or simply exploring molecular data.
Here’s how you can leverage Visual Presets for your molecular modeling needs:
Your First Steps with Visual Presets
Accessing Visual Presets in SAMSON is intuitive. Simply navigate to the Home > Visual Preset or Visualization > Visual Preset menu. There, you’ll find a range of default visual presets ready to be applied. For instance, the Protein-ligand preset can quickly define a polished look for protein-ligand models, ideal for structural studies or communication with collaborators.
Here’s an example of applying a visual preset, highlighting how simple and impactful this can be:
When you apply a preset, it automatically creates a corresponding folder in your document, organizes the visual models it generates, and even groups nodes related to your selections. This means you can customize, revisit, or fine-tune your visualizations with ease.
Customizing and Creating Visual Presets
What if the default presets don’t fully fit your need? That’s not a problem. You can create your own visual presets or modify existing ones thanks to the Visual Preset Editor. Whether you want to tweak visualizations of particular atoms, add hidden actions, or apply specific color schemes, crafting a tailored preset is a seamless process.
Each visual preset is composed of steps, and each step has four key components:
- A node selection, like pulling out elements such as “Ligands” or “Heavy atoms.”
- Optional actions, such as labeling particular atoms, hiding unwarranted details, or zooming into critical areas.
- An optional visual model, for instance, switching to Van der Waals representation, ribbons, or licorice-style visuals.
- An optional color scheme, such as color per chain, constant scheme, or dynamic attributes like occupancy.
Step-by-step modifications or additions allow you to build presets based on specific scientific needs or artistic preferences. For advanced customization, you can compose specialized node selections using the Node Specification Language (NSL).
Below are visual examples outlining the intuitive customization processes:
1. Adding new steps to your presets:
2. Choosing a selection tailored to your nodes:
3. Applying visual models to boost interpretability:
4. Integrating colorization preferences for a publication-ready output:
Once satisfied, don’t forget to save your presets. They’ll be ready for use whenever you launch SAMSON, enabling consistent and time-saving workflows moving forward.
Why Use Visual Presets?
The key value of Visual Presets lies in efficiency. For example, when analyzing large protein-ligand systems, coloring per-residues or simplifying visualizations can be critical. Visual Presets reduce repetitive manual setups, enabling researchers to dedicate more energy to interpretation rather than preparation.
Additionally, users can streamline collaboration with colleagues by sharing preset designs or submitting innovative presets to SAMSON for broad usage.
