Box 808, L-352 Fax (925) 422-6892 Livermore, CA 94551-0808 These LabVIEW 4 VIs read and save numeric arrays as Igor (Wavemetrics Corp.) binary-format files. The Igor file version is 2, for use with Igor 1.2 or higher. The newer version 3 format, featuring multiple waves in a single file, is not supported. All Vis are portable among all LabVIEW platforms (Mac, Windows, Sun, HP, Concurrent) without modification. Data files written on one platform are readable on any other platform. LabVIEW 4 or higher is required. There are five VIs to write data: for single (SGL) and double-precision (DBL) floating point, and for I8, I16, and I32 integer numbers. Read Igor Binary File reads all formats except complex. All of IgorÍs wave data features are supported ( including X and Y scaling and labels, and wave notes). Full documentation of the data structures in this file format is available in WavemetricsÍ Technical Note 003, Igor Binary File Format.. Information is also available through the Get I n f o ... command on each VI and through the Description... fields on each control, accessible through the LabVIEW Help window. Note that complex waves are not supported.
