Hi, I am running into troubles with R1rho dispersion fits. In brief, we get totally unrealistic values for phi_ex (>10000) and k_ex (<1 s-1). It seems that the default parameter limits for phi_ex are such that there is only a lower bound (0) but no upper bound. This can result in physically totally meaningless situations, like a strong R1rho dispersion profile, with a fitted exchange rate constants of 0.2 s-1…. I would like to have some control over the grid search and the analysis.
My questions: * does anyone know how to set/change the grid parameter range? Has anyone run into similar issues? * does anyone have a script to do the analysis without going through the auto-analysis? The manual is (for me) not useful to design the analysis. Thanks Paul 1.
