navis.dist_between

navis.dist_between(x, a, b)

Get the geodesic distance between nodes in nanometers.

Parameters:

• x (TreeNeuron | MeshNeuron | NeuronList) – If NeuronList must contain only a single neuron.

• a (int) – Node IDs (for TreeNeurons) or vertex indices (MeshNeurons) to check the distance between.

• b (int) – Node IDs (for TreeNeurons) or vertex indices (MeshNeurons) to check the distance between.

Returns:

distance in nm

Return type:

int

distal_to()

Check if a node A is distal to node B.

geodesic_matrix()

Get all-by-all geodesic distance matrix.

navis.segment_length()

Much faster if you have a linear segment and know all node IDs.

Examples

>>> import navis
>>> n = navis.example_neurons(1)
>>> d = navis.dist_between(n,
...                        n.nodes.node_id.values[0],
...                        n.nodes.node_id.values[1])
