A JupyterLab extension to explore and visualize HDF5 file contents.

jupyterlab-h5web

A JupyterLab extension to explore and visualize HDF5 file contents. Based on h5web.

WARNING: This extension is still in active development. Please report any encountered issue.

Requirements

• JupyterLab ~= 2.0 (not JupyterLab 3)

Install

Note: You will need NodeJS to install the extension.

pip install jupyterlab_h5web
jupyter lab build

To enable support for additional filters such as blosc or bitshuffle:

pip install jupyterlab_h5web[full]
jupyter lab build

This will install hdf5plugin in addition to the extension.

Usage

Once the extension is installed, you can double-click on an HDF5 file or right-click Open with -> h5web to launch a tab.

This tab is composed of a sidebar, where you can explore the structure of the HDF5 file, and of a main area where the visualization of the selected entity takes place. This visualization is controlled by the upper-right button that can toggle between:

• Display: visualize datasets using Line, Heatmap or Matrix visualizations.
• Inspect: show the metadata and attributes of any entity

Supported file formats

jupyter-h5web detects HDF5 files based on their file extensions. The viewer works for the following extensions:

• "Classic" HDF5: .h5, .hdf5
• NeXus: .nexus, .nx, .nxs
• CXI: .cxi

For other types of files, you can change the extension to one of the supported extensions or, if it is widespread, open an issue to discuss its support.
