About

nd2reader is a pure-Python package that reads images produced by NIS Elements 4.0+. It has only been definitively tested on NIS Elements 4.30.02 Build 1053. Support for older versions is being actively worked on. The reader is written in the pims framework, enabling easy access to multidimensional files, lazy slicing, and nice display in IPython.

Documentation

The documentation is available here.

Installation

The package is available on PyPi. Install it using:

pip install nd2reader

If you don't already have the packages numpy, pims, six and xmltodict, they will be installed automatically if you use the setup.py script. Python >= 3.5 are supported.

Installation via Conda Forge

Installing nd2reader from the conda-forge channel can be achieved by adding conda-forge to your channels with:

conda config --add channels conda-forge

Once the conda-forge channel has been enabled, nd2reader can be installed with:

conda install nd2reader

It is possible to list all of the versions of nd2reader available on your platform with:

conda search nd2reader --channel conda-forge

ND2s

nd2reader follows the pims framework. To open a file and show the first frame:

from nd2reader import ND2Reader
import matplotlib.pyplot as plt

with ND2Reader('my_directory/example.nd2') as images:
  plt.imshow(images[0])

After opening the file, all pims features are supported. Please refer to the pims documentation.

Backwards compatibility

Older versions of nd2reader do not use the pims framework. To provide backwards compatibility, a legacy Nd2 class is provided.
