pynrrd is a pure-Python module for reading and writing NRRD files into and from numpy arrays.
The module's only dependency is numpy.
Install via pip and PyPi repository (recommended)
pip install pynrrd
Install via pip and GitHub
pip install git+https://github.com/mhe/pynrrd.git
Install from source (recommended for contributing to pynrrd)
For developers that want to contribute to pynrrd, you can clone the pynrrd repository and install it using the following commands:
git clone https://github.com/mhe/pynrrd.git cd pynrrd pip install .
or, for the last line, instead use:
pip install -e .
to install in 'develop' or 'editable' mode, where changes can be made to the local working code and Python will use the updated pynrrd code.
import numpy as np import nrrd # Some sample numpy data data = np.zeros((5,4,3,2)) filename = 'testdata.nrrd' # Write to a NRRD file nrrd.write(filename, data) # Read the data back from file readdata, header = nrrd.read(filename) print(readdata.shape) print(header)
Run the following command in the base directory to run the tests:
python -m unittest discover -v nrrd/tests
