EyeFlow Waveform Fixture Extractor 0.1.0

EyeFlow Waveform Fixture Extractor 0.1.0

A standalone Windows application for creating compact waveform-only HDF5
fixtures from EyeFlow outputs.

Use

1. Download EyeFlowWaveformFixtureExtractor.exe.
2. Verify it against EyeFlowWaveformFixtureExtractor.exe.sha256.
3. Double-click the executable.
4. Choose an EyeFlow H5 file or folder and a separate output folder.
5. Use Validate inputs first, then Extract fixtures.

No Python installation is required.

Privacy boundary

The extractor copies only an explicit allow-list of numeric artery/vein
waveforms, beat timing, and optional per-beat signals. It does not copy source
filenames, HDF5 attributes, images, masks, maps, the full retinal velocity
volume, or acquisition metadata.

Extracted waveforms remain patient-derived and potentially sensitive. Follow
the applicable data-governance rules and do not upload them to a public
repository without explicit approval.

Verification

• Built from commit 8df0d2a with Python 3.12.10 and PyInstaller 6.21.0.
• Packaged executable self-test completed successfully on a full EyeFlow H5.
• The test input was reduced from 516.85 MB to a 539.3 KiB fixture.
• All 67 EyeFlow repository tests passed.
• Ruff reported no issues in the extractor source and tests.
• Microsoft Defender found no threats in the published executable.

The executable is not code-signed. Windows SmartScreen may show an
unrecognized-app warning; verify the SHA-256 checksum before running it.
