Hi, The following is a copy of my post to the NESSY mailing list at https://mail.gna.org/public/nessy-users/2014-03/msg1.html. This replicated here on the relax-users mailing list to be used as a permanent relax reference (parts of it might be copied into the relax wiki or manual in the

Hi Ivanhoe. I remember that Edward added a section to the manual about running time, and probably somewhere on the relax mailing list that question is answered. But it depends on how many spins, computer power, and how many CPU. But I think that anything between a day and a week is expected

Hi, This addition was for the relaxation dispersion analysis and is in section 10.14.2 Dispersion GUI mode - computation time. The text is: The time required to complete these two analyses is highly dependent on the computer being used as well as how many nodes can be used for running the

Dear Justin. If you have R1 values measured from an experiment. And you have R1rho intensities measured as variations of spin-lock time, spin-lock offset and spin-lock field/power, you can perform R1rho analysis in relax. If we just think of model DPL94, you would in relax get fitted R20(or
