<div class="">The first release candidates for both NeXpy v1.0.0 and nexusformat v1.0.0 have been released (<a href="https://pypi.org/project/NeXpy/1.0.0rc1/" class="">https://pypi.org/project/NeXpy/1.0.0rc1/</a>). The conda-forge channel does not support pre-releases,
but you can install v0.14.8 and v0.7.8, respectively, which are nearly identical. If you use NeXpy, please install the latest versions and report any issues to their respective Github pages in <a href="https://github.com/nexpy" class="">https://github.com/nexpy</a>.</div>

<div class=""><u class="">NeXpy</u></div>
<div class=""><br class="">
</div>
<div class="">NeXpy provides a high-level Python interface to NeXus data, within a simple GUI that combines a tree view of loaded files, Matplotlib panes to visualize multidimensional arrays, and an IPython shell for manipulating the data and metadata. NeXpy
is intended to be a simple, intuitive, interactive toolbox that allows users to explore ways of modeling NeXus data, with minimal overhead, and to create new NeXus-conforming data files without expert knowledge of the file format. NeXpy makes it easy to view
arbitrary 1D and 2D slices and projections of multi-dimensional data and to compare data from multiple datasets.</div>
<div class=""><br class="">
</div>
<div class="">A built-in script editor allows new data analysis methods to be developed, tested, and refined. The underlying Python API for reading and writing NeXus files is provided by the nexusformat package, which utilizes h5py. NeXpy also contains a GUI
interface to the lmfit module for fitting 1D data. </div>
