dynetworkx.IntervalGraph.load_from_txt

static IntervalGraph.load_from_txt(path, delimiter=' ', nodetype=None, intervaltype=<class 'float'>, comments='#')
Read interval graph in from path.
Every line in the file must be an edge in the following format: “node node begin end”. Both interval times must be integers or floats. Nodes can be any hashable objects.
Parameters:
  • path (string or file) – Filename to read.
  • nodetype (Python type, optional) – Convert nodes to this type.
  • intervaltype (Python type, optional (default= float)) –
  • interval begin and end to this type. (Convert) –
  • must be an orderable type, ideally int or float. Other orderable types have not been fully tested. (This) –
  • comments (string, optional) – Marker for comment lines
  • delimiter (string, optional) – Separator for node labels. The default is whitespace.
Returns:

G – The graph corresponding to the lines in edge list.
Return type:

IntervalGraph

Examples

>>> G=dnx.IntervalGraph.load_from_txt("my_dygraph.txt")

The optional nodetype is a function to convert node strings to nodetype.

For example

>>> G=dnx.IntervalGraph.load_from_txt("my_dygraph.txt", nodetype=int)

will attempt to convert all nodes to integer type.

Since nodes must be hashable, the function nodetype must return hashable types (e.g. int, float, str, frozenset - or tuples of those, etc.)
