spacenet.helpers.get_nodes_and_labels(spatial_network, node_label_name='label')

A function to extract node indices and labels from a spatial network. This can be used to get the node indices and corresponding labels (e.g. cell types or gene expression levels) for nodes in the network.

Parameters:

spatial_networknetworkx.Graph

The spatial network from which to extract node indices and labels. Nodes should be indexed by integers and have a node attribute corresponding to the labels.

node_label_namestr, optional

The name of the node attribute corresponding to the labels to extract. Default is ‘label’.

Returns:

nodesnumpy.ndarray

An array of node indices for nodes in the spatial network that have the specified label attribute.

labelsnumpy.ndarray

An array of labels corresponding to the specified label attribute for each node in the spatial network that has that attribute.
