HDF5 Browser — kvot ab

Drop HDF5 files here

Load HDF5 from URL

Enter the direct URL to an .h5 / .hdf5 file, or to an Ecolego assessment (.eas).

Private GitHub repository

A fine-grained token with Contents: Read-only on that one repository. It is kept for this tab only and is never written to disk.

Sample Data

Select HDF5 files to load from the server.

HDF5 Browser for VS Code

This browser as an extension for Visual Studio Code: .h5, .hdf5 and .he5 files open in it as an editor, with everything this page does, and a file of any size is read a piece at a time.

Looking for the latest version…

Download the extension with the button below.
In VS Code, open the Extensions view (⇧⌘X, or Ctrl+Shift+X), choose Install from VSIX… in its … menu and pick the file. Or, in a terminal: code --install-extension hdf5-browser.vsix
Reload the window when VS Code asks. From then on the extension keeps itself up to date: it installs each new version from this site by itself, and HDF5 Browser: Check for Updates looks at once.

HDF5 Browser

An interactive browser for exploring and visualising HDF5 data files.

Getting Started

Load files — drag & drop .h5 / .hdf5 files onto the page, click Add Files, or use URL to fetch from a remote server.
Browse — expand groups in the tree on the left to explore the file structure.
Select — click a dataset to view its attributes and chart.

Tips

Ctrl-click (⌘ on Mac) datasets to compare multiple in one chart.
Ctrl-click groups that draw a chart of their own to draw them together, a panel each, or in one chart with Same chart.
Use the search bar to filter the tree — supports * wildcards and / full-path search.
Load multiple files and use the ∩ (intersect) or ∪ (union) toggle to combine trees.
An Ecolego assessment (.eas) opens too: each run it keeps opens as a file of its own.
Large files open at once: from 256 MB a file is read from disk as you look at it, not loaded whole.
Toggle Dynamic Legend to auto-hide traces outside the current view.
Right-click the chart to copy or download data as CSV / Excel.
Right-click in the tree to send the selection to the User Interface for statsmodels for statistics, or to save it as an HDF5 file; values are drawn from its distributions, 1,000 or as many as you choose.
Python, by the chart's controls, writes the chart as a matplotlib script that draws it from the HDF5 files.

Chart Controls

Scale selectors — switch axes between linear and log scales, and give an axis's unit a prefix: k shows Bq as kBq, the values divided by 1000.
Show Total — for radionuclide groups, overlay a summed trace.
Show Ratio — when two files are loaded, display max-value ratios per isotope.
Show Max — append maximum trace value to each legend entry (disabled when Show Ratio is active).
Preset views — choose one in the list by the chart. The gear beside it opens the axis presets window: the chart's axes, to set by hand, and the saved presets, to use, edit, update or delete. Drag it aside by its title bar while you work on the chart.
