Retrieve the actual x,y position of specified nodes.

Parameters

  • nodes_names (str or list or int or None) – List of nodes or None. If node list: list of node names or SUIDs, comma-separated string of node names or SUIDs, or scalar node name or SUID. Node names should be found in the name column of the node table. If list is None, default is all nodes.

Returns

with index as node_names values and columns x and y containing coordinates

Return type

Raises

  • CyError – if network name or node doesn’t exist

  • requests.exceptions.RequestException – if can’t connect to Cytoscape or Cytoscape returns an error
