dynamo.vf.curvature

dynamo.vf.curvature(adata, basis='umap', vector_field_class=None, formula=2, **kwargs)

Calculate curvature for each cell with the reconstructed vector field function.

Parameters

• adata (AnnData) – AnnData object that contains the reconstructed vector field function in the uns attribute.

• basis (str or None (default: umap)) – The embedding data in which the vector field was reconstructed.

• vector_field_class (vectorfield) – If not None, the divergene will be computed using this class instead of the vector field stored in adata.

• formula (int (default: 2)) – Which formula of curvature will be used, there are two formulas, so formula can be either {1, 2}. By default it is 2 and returns both the curvature vectors and the norm of the curvature. The formula one only gives the norm of the curvature.

Returns

adata – AnnData object that is updated with the curvature key in the .obs.

Return type

AnnData
