SI supplementary units - the dimensionless and hidden radian unit.

Hi, Warning: If hard core NMR or physics theory is not to your taste, please do not read any further! This post is mainly for later reference, but is quite important for understanding the relaxation equations in NMR, and actually any rotational physical process. It is important for the model-fr

Very low Tm in model-free analysis

Hello, I have some trouble using relax with my data. I have data at 600 MHz only so I use models m0,m1,m2,m3,m9 with the classic approach of starting with an initial estimate of the Tm, with a modified versiion of the script mf_multimodel.py. which includes model selection and diffusion tensor op

Re: Very low Tm in model-free analysis

Hi, This problem you have encountered is that of artificial chemical exchange. This is quite well documented by Tjandra et al., 1995. The instability has been compounded by the use of only single field strength data as the physics theory cannot differentiate between Rex (which scales quadratical
