When working on molecular modeling, discovering correlations or patterns in your analysis can be crucial in understanding complex behaviors. This is where the Custom Scatter tool in SAMSON offers a powerful, streamlined solution to assist you in visualizing trends and relationships between two observables. Let’s walk through how you can make use of this feature to enhance your molecular studies effectively.
Why Use the Custom Scatter Tool?
The Custom Scatter analysis allows you to compare two saved scalar analyses directly against each other, making it a quick and efficient way to unveil relationships such as correlations, anticorrelations, clusters, or transition pathways in your dataset. Essentially, this tool gives you a visual representation of how two properties or variables behave relative to one another.
For instance, you might be investigating relationships like:
- Distance vs Energy
- Root-Mean-Square Deviation (RMSD) vs Radius of Gyration
- Solvent Accessible Surface Area (SASA) vs Distance
These plots not only help answer specific scientific questions but often serve as a starting point for other advanced visualizations like 2D density maps or energy landscapes.
Key Features and Inputs
Here’s what you need to know before diving into the tool:
- The Custom Scatter is a derived analysis that uses the Analysis Tray instead of direct atom selections.
- You need exactly two saved scalar analyses in the tray to create the scatter plot.
- When the two analyses originate from the same path and remain frame-linked, the scatter plot can dynamically connect to the current frame, enabling interactive explorations.
How to Add and Analyze Your Scatter Plot
Setting up your scatter plot involves just a few straightforward steps:
- Open the Path Analyzer in SAMSON.
- Prepare or reuse two scalar analyses saved in the Analysis Tray.
- Choose the Custom Scatter option under Observable.
- Select the two scalar analyses that you want to compare.
- Finally, click on Add Scatter to generate your plot.
In the resulting scatter plot, each point represents a sampled pair of scalar values. If the analyses are frame-linked, you can even click on specific points to move the path to the corresponding frame, facilitating deeper exploration of the dataset. This interactivity is valuable, especially when mapping out transition pathways or identifying particular events in a simulation trajectory.
Optimizing Your Analysis
To get the most from the Custom Scatter tool:
- Choose scalar analyses that align with your research question. The clearer your goal, the more insightful your scatter plot will be.
- Use this tool as a stepping stone. Once you identify significant trends, you can move forward to generating a 2D density map or an energy landscape for a more detailed exploration of the data.
Conclusion
The Custom Scatter tool in SAMSON bridges the gap between curiosity and discovery by giving molecular modelers a flexible and interactive way to visualize correlations.
