Thanks Henry, that indeed was the catch. To be true, I wasnt even aware of this NC_proc, but did pay attention to whatever XWinNMR showed in edp and even tried rpar/wpar the processing parameters. Apparently you know finer details of the software, I have this question for some time and will appreciate a response: How to do backward and then forward linear prediction on a 3D in XWinNMR? I know it can be done on 2D or by using nmrPipe.

Best regards

Hi Mandar,

When the data is processed in XWinNMR and imported in Sparky (direct
read or bruk2ucsf), the ratio for all residues comes above 10 and
obviously doesnt make any sense. Same data analyzed in Brukers
Aurelia gives proper acceptable values of 1.

You should check the NC_proc parameter in XwinNMR, which scales the
intensity. Type dpp to see the settings and process both the NOE and
NONOE spectra with xfb nc_proc 3 or whichever value suits best.

Kind regards,

Henry
