Pure python module for reading and writing NRRD files.
pynrrd is a pure-Python module for reading and writing NRRD files into and from numpy arrays.
v1.0+ requires Python 3.7 or above. If you have an older Python version, please install a v0.x release instead.
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.
The tests can be run via the following command from the base directory:
python -m unittest discover -v nrrd/tests
Format and Lint code
This repository uses pre-commit hooks to run format and lint the code and they are enforced in CI. See [pre-commit](https://pre-commit.com)
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)
