navis.TreeNeuron.prune_by_strahler

TreeNeuron.prune_by_strahler(to_prune, inplace=False)

Prune neuron based on Strahler order.

Will reroot neuron to soma if possible.

Parameters:

• to_prune (int | list | range | slice) –

  Strahler indices to prune. For example:

  1. to_prune=1 removes all leaf branches

  2. to_prune=[1, 2] removes SI 1 and 2

  3. to_prune=range(1, 4) removes SI 1, 2 and 3

  4. to_prune=slice(1, -1) removes everything but the highest SI

  5. to_prune=slice(-1, None) removes only the highest SI

• inplace (bool, optional) – If True, operation will be performed on itself. If False, operation is performed on copy which is then returned.

Return type:

Optional[TreeNeuron]
