Edited sentence: An open source project known as Sashimi offers a collection of converter programs for some common mass spectrometric file formats.Bruker's free CompassXport tool will nicely generate mzXML (and now mzData) files for many of their native file formats.Currently there are converters available at Sashimi for ThermoFinnigan (Xcalibur format using ReAdW), Micromass (MassLynx format using MassWolf) and SCIEX/ABI (SCIEX/ABI Analyst using mzStar)
