REX is a community-oriented software tool for NMR Relaxometry. This means, above all, that it is designed to read raw data from any source. However, given the profusion of currently used data formats, not all NMR vendors are yet supported. If your data files are not simple n-column text files, Stelar files (SDF), Bruker folders (TopSpin), or Oxford Instruments files (RiDat), or if you are not sure, simply write us, send us a sample of your data file(s) and we will be glad to make sure that REX can read it.
