TMD

A python package for the topological analysis of neurons.

The TMD performs the topological analysis of neuronal morphologies and extracts the persistence barcodes of trees.

This Python module includes:

Basic loading of neuronal morphologies in swc and h5 file format.
Extraction of the topological descriptors of tree morphologies.
Visualization of neuronal trees and neurons.
Plotting persistence diagrams, barcodes and images.

Installation

This package should be installed using pip:

pip install TMD

For installation of optional viewers:

pip install TMD[viewer]

Usage

# Import the TMD toolkit in IPython
import tmd

# Load a neuron
neuron = tmd.io.load_neuron('input_path_to_file/input_file.swc')

# Extract the tmd of a neurite, i.e., neuronal tree
pd = tmd.methods.get_persistence_diagram(neuron.neurites[0])
