Extensions

Extensions exist so the default viewer can stay lightweight while specialized workflows (MRS, BIDS, etc.) live in their own packages. This keeps the GUI small for scanner environments but still lets teams build richer interfaces.

BrkRaw Viewer supports optional extensions via the brkraw.viewer.hook entry point. Extensions can add a tab and dataset-specific UI, and they can work alongside converter hooks or CLI hooks because they share the same rule/spec system.

Installing extensions

Install the extension package in the same environment as brkraw-viewer:

pip install brkraw-mrs

Selecting an extension

Extensions are selected manually in the Extensions tab. The default value is None, which keeps the core viewer active.

The brkraw-mrs extension renders its underlay preview inside the MRS tab to keep the core viewer stable. Underlay controls live in the MRS tab alongside the spectrum view.
