Hello Users, I am new to the world of model-free analysis, I have my first data set of R1, R2, and NOE at 800mHz, at 35C and 50C. I would like to use relax as the program for analysis, as it seems both robust and user-friendly. Unfortunately, it would be quite difficult for me to acquire data at a lower field since my protein is ~40kDa and the fact that the 600mHZ spectrometers at my university can only decouple, but not detect, 15N. I am curious, what catastrophic event would occur if I were to try to use relax with only data sets from 800mHz? I've read through the references, but could someone make it abundantly clear to me why this is a horrible idea? Otherwise, I will have to use modelfree, and after reading through the d'Auvergne/Gooley 2008 J Biomol NMR papers, I feel like that won't be so great either. Thank you, Sean Moro PhD candidate University of California, Irvine.
