biomol.core.EdgeFeature

class EdgeFeature(value, src_indices, dst_indices)

Bases: Feature

A feature associated with edges (pairs of nodes) in a structure.

Parameters:

• value (np.ndarray) – A numpy array where the first dimension corresponds to the edges.

• src_indices (NDArray[np.integer]) – A 1D numpy array of source node indices for each edge.

• dst_indices (NDArray[np.integer]) – A 1D numpy array of destination node indices for each edge.

Attributes

value	The underlying numpy array representing the feature data.
src_indices	Source node indices of the edges.
dst_indices	Destination node indices of the edges.
dst	Return the destination node indices of the edges.
dtype	Return the data type of the feature.
ndim	Return the number of dimensions of the feature.
nodes	Return the unique node indices involved in the edges.
shape	Return the shape of the feature.
size	Return the total number of elements in the feature.
src	Return the source node indices of the edges.

Methods

copy	Return a deep copy of the edge feature.
crop	Crop the feature to only include the specified indices.
max	Return the maximum of the feature along the specified axis.
mean	Return the mean of the feature along the specified axis.
min	Return the minimum of the feature along the specified axis.
sum	Return the sum of the feature along the specified axis.
