What is the difference between Gene and Gene Group Layers?¶
Gene Layer: shows one gene.
Gene Group Layer: combines multiple genes into a single visualization.
| Aspect | Gene Layer | Gene Group Layer |
|---|---|---|
| N Genes | Exactly one. | Two or more. |
| Primary Purpose | Inspect the precise spatial pattern of a single gene marker. | Visualize the aggregate expression of a set of related markers as one coherent visual element. |
| Typical Use Case | Verify a specific cell-type marker's spatial localization. | Combine a set of markers (e.g. all marker genes of a specific cell type) to visualize the cell type's density. |
| Visual Appearance | Colored independently based on the selected gene's color setting. | Rendered as a single layer on the map with all member genes sharing the same color. |
| Interpretation | Directly represents the expression level of that single gene. | Represents a combined, normalized spatial signal from all member genes. |
