NAVis is a Python 3 library for Neuron Analysis and Visualization with focus on hierarchical tree-like neuron data.
NAVis is on ReadTheDocs.
- interactive 2D (matplotlib) and 3D (vispy or plotly) plotting of neurons
- virtual neuron surgery: cutting, pruning, rerooting
- clustering methods (e.g. by connectivity or synapse placement)
- fetch neurons directly from neuromorpho.org
- Python bindings for R neuron libraries (e.g. nat, rcatmaid, elmr)
- interfaces with Blender 3D and Cytoscape
See the documentation for detailed installation instructions, tutorials and examples. For the impatient:
pip3 install navis

NAVis is a generalization of pymaid and some of the code is still being refactored. Basic functionality is implemented but there are still some TO-DOs:
- update example notebooks and docs
- update Cytoscape interface
- update Blender interface to Blender 2.8
- write new tests
NAVis is inspired by and inherits much of its design from the excellent nat & friends R packages by Greg Jefferis, Alex Bates, James Manton and others.
NAVis implements or provides interfaces with algorithms described in:
