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.
The documentation is available here.
The package is available on PyPi. Install it using:
pip install nd2reader
If you don't already have the packages
xmltodict, they will be installed automatically if you use the
nd2reader is an order of magnitude faster in Python 3. I recommend using it unless you have no other choice. Python 2.7 and Python >= 3.4 are supported.
Installation via Conda Forge
nd2reader from the
conda-forge channel can be achieved by adding
conda-forge to your channels with:
conda config --add channels conda-forge
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
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)
After opening the file, all
pims features are supported. Please refer to the pims documentation.
Older versions of
nd2reader do not use the
pims framework. To provide backwards compatibility, a legacy Nd2 class is provided.
