GRID_SPREAD#
Python object: phenotypic.schema._grid_spread.GRID_SPREAD
Quantify within-well colony dispersion using pairwise centroid distances.
Compute the sum of squared pairwise Euclidean distances between all colony centroids in each grid section. High values indicate multiple dispersed objects within a single well – a sign of over-segmentation, fragmented growth, or invasive spreading.

Description |
|---|---|
|
Sum of squared pairwise Euclidean distances between all unique colony pairs within a grid section. Quantifies spatial dispersion of colonies in a grid cell. Higher values indicate greater spread from the section center, suggesting over-segmentation, multi-detections, or colonies growing beyond expected boundaries. Used to identify problematic grid sections requiring refinement or quality review. |
