CellGPS is a standalone Windows application for revealing multiscale tissue architecture from spatial omics data through radius-free distance hierarchies. It represents each spatial population by directed nearest-neighbour distance profiles, applies hierarchical clustering to these profiles, and derives dendrogram-based summaries including StructureMap visualizations and the Spatial Separation Score (SSS). The workflow supports both cell-type and single-transcript analyses without requiring a user-defined spatial radius or neighbourhood cutoff. Transcript-level analysis can be performed without cell segmentation. The graphical interface provides a no-code workflow for loading spatial omics data, running the analysis, and exporting interpretable figures and tables.
