What are the difference between Gene Layer versus Gene Group Layer?

A Gene layer shows one gene. A Gene Group layer combines multiple genes into a single visualization.

Aspect	Gene	Gene Group
Definition	A layer showing one gene	A layer combining multiple genes
Number of genes	One	more than one
Purpose	View the spatial pattern of a single gene	View a related set of genes together
Typical use	Inspect a specific marker	visualize the aggregate expression of a set of related genes (e.g., cell type markers) as one coherent visual element,
Interpretation	Directly tied to one gene	Represents a combined signal from multiple genes
Color behavior	The gene layer uses its own color	All genes in the gene group are colorized with the same color
Layer behavior	Added as one gene layer	Added as one grouped layer
