RADIAL_EXPANSION#
Python object: phenotypic.schema._radial_expansion.RADIAL_EXPANSION
Radial expansion measurements for filamentous fungal colonies.
Quantifies branching morphology by decomposing colony structure into a dense core and peripheral branches via PELT changepoint detection on radial density profiles, followed by skeleton-based branch tracing. Includes runner detection for identifying anomalously long branches.

Description |
Type |
|---|---|---|
|
Trimmed mean of branch path lengths, excluding detected runner. Represents the typical radial expansion distance of hyphae from the core boundary, robust to single-runner outliers. |
|
|
Arithmetic mean of all branch path lengths from core boundary to branch tips. Includes runner if present. Reflects overall average colony reach. |
|
|
Median branch path length. Robust to outliers and provides a typical expansion distance. |
|
|
Number of skeleton branches extending from the core boundary to peripheral tips. Higher counts indicate denser branching morphology. |
|
|
Length of the longest branch path in pixels. When a runner is detected, this equals RunnerLength. |
|
|
Path length of the detected runner branch (the single longest outlier). NaN if no runner detected. |
|
|
Boolean flag (0 or 1) indicating whether an outlier runner branch was detected for this colony. |
|
|
Radius of the dense colony core as determined by PELT changepoint detection on the radial density profile. Pixels within this radius of the intensity-weighted centroid are excluded from skeleton analysis. |
