Hi, Here is a work around, using nmrpipe you can create a pseudo3D dataset from the separate spectra then analysis will be able to cope with the data. The scripts to do this are in the nmrpipe example data demo/relax (link here: demo.tar <http://www.ibbr.umd.edu/nmrpipe/demo.tar>). If you have any problems with your specific dataset let me know and I can dig out the scripts I used to do this on my own data. -Jo > On 11 Oct 2018, at 23:43, Brian Smith <[log in to unmask]> wrote: > > That's a restriction that should be relaxed.

I have all the spectra set (peak picked) and the CPMG serie created (frequency;Hz). The problem is that i cannot set the ref plane (the button is greyed) so it cannot calculate the R2eff = ln(I0/I)/tau and returns errors for the fit peaks. Am i do it all wrong?
