Igor Binary Wave (.ibw)
.ibwWaveMetrics Igor Pro (exporting a single wave)
What it is
A single named 1D data array ("wave", in Igor's terminology) exported from WaveMetrics Igor Pro — written against Igor's own published Technical Note TN003 format specification.
Who produces it
Researchers using WaveMetrics Igor Pro who export one wave at a time rather than a whole packed experiment (see the .pxp page for that case).
What we read / what we don't read
What we read
- 1D numeric waves (version-5 wave header — the layout used by Igor Pro 5 and all later versions)
- The wave's X-axis, reconstructed from its stored scaling factors (matching Igor's own TN003 formula)
What we don't read
- Text waves, complex-number waves, and multi-dimensional (2D+) waves
- Wave header versions older than 5 (pre-Igor-5 files)
How to import it into AltaiPlot
- Open AltaiPlot and drag your .ibw file onto the window, or use File → Import.
- AltaiPlot detects the Igor Binary Wave signature and reads it directly — no external dependency involved.
- The wave's data lands as a plotting-ready column with its reconstructed X-axis.
