Hi Stefano, For what has happened here, you need to open up your log file. Did you use relax with the --log or --tee command line options to capture the messages? If you go to the start of the messages, you will very likely find RelaxWarnings which say something like deselecting the spin due to missing {relaxation data; bond vector information; etc.} or due to something else in the set up. In relax, everything that happens is sent to the log so you can always go back and see exactly what happened. I hope this solves your problem.

Hi Edward, an additional question: in the output file I noticed that the last four residues at the C-terminus, for which I provided relaxation data, are not included. Any reason for it? (for the previous 9 residues we did not have the assignment because they are not observed due to intermediate exchange phenomena that broaden them too much to be visible, while the last four residues are clearly visible and they appear to be very mobile, and yet, no output from relax.
