Re: dimerRe: dimerHi 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.
