Requirements

Before installing taufactor, download the most recent version of PyTorch. Ensure you have pytorch>=1.10 installed in your Python environment.

For example, for a Linux machine with CUDA GPU

conda install pytorch pytorch-cuda=11.7 -c pytorch -c nvidia

Quickstart

To install TauFactor via PyPI

pip install taufactor

To extract effective diffusivity and tortuosity factor from your data:

import taufactor as tau
import tifffile

# load image
img = tifffile.imread('path/filename')
# ensure 1s for conductive phase and 0s otherwise.

# create a solver object with loaded image
s = tau.Solver(img)

# call solve function
s.solve()

# view effective diffusivity and tau
print(s.D_eff, s.tau)

Tests

To run unit tests navigate to the root directory and run

pytest
