Hi Sam, For relax, you simply input the peak lists. Using the spectrum.read_intensities user function (http://www.nmr-relax.com/manual/spectrum_read_intensities.html), you can load in peak intensities - either height or volumes - from many different spectral software programs. This includes Sparky, XEasy, NMRView, NMRPipe seriesTab, and a generic column formatted text file (the Bruker Dynamics Centre format is also supported). relax is designed so that users never have to perform format conversions to input or output data. If a format conversion is necessary, I would insist on a new support request being created and an example data file attached to it. Then the support for the format can be quickly added to relax (by first implementing system tests).
The problem with conversions is the chance of data loss or a mistake being made. But the conversions in relax are all extensively and repeatedly checked via the comprehensive test suite, so that you can be sure that no mistakes are made: $ relax --test-suite --time But just with all other analysis software, you should always be on the look out for problems, as all software contains bugs. So software can be treated as a black box, but always be vigilant and sceptical of all results. Oh, thanks to advances implemented by Troels, you can now simultaneously load all peak lists with one spectrum.read_intensities user function call. This is especially useful if you are using the GUI.
