Dear all, I'm a new user of CcpnNMR and I have some questions. 1: In the noesy peak list, must we make a reference between 2 protons of the asparagine, for example, to calibrate the volume for the distance??? 2: What is the difference between the peak list and the shiftlist I pick all the peak in my NOESY experiment, these peaks appear in the noesylist, corresponding to the peak list. When I try to export in the cns format, I obtain an empty file. I don't know how to obtain the different files corresponding to the spin system (TOCSY) and the constrain file (NOESY)??? 3:When I run Aria, where is located the input files (spin system and noesy files)??? Thanks in advance, Nathalie Evrard
