Re: field strength off-resonance R1rho constant relax time relaxation dispersion

Dear Edward, Thanks for providing help and insights. I used an improved script. The scripts is able to calculate the R2eff and the omegaeffective properly, but it is not able to fit any model. It also sees dispersion point as a constant 1500 Hz (see attached file in results/R2eff/disp_55_N.out).

Dear Edward, I am trying to use 'relax' for the off-resonance R1rho constant-relaxation-time relaxation dispersion using R1rho_analysis.py script available as sample script with relax. The following is the section where I have question:
