bento.tl.second_moment

bento.tl.second_moment(sdata, shape_key, recompute=False) → None

Compute second moment of each shape relative to its centroid.

The second moment measures the spread of points in the shape around its center.

Parameters:

• sdata (SpatialData) – Input SpatialData object

• shape_key (str) – Key in sdata.shapes containing shape geometries

• recompute (bool, default False) – Whether to force recomputation if feature exists

Returns:

Updates sdata.shapes[shape_key] with: - ‘{shape_key}_moment’: Second moment value for each shape

Return type:

None
