Hi Atul, As Troels asked, could you create a support request with the link https://gna.org/support/?func=additemgroup=relax and attach the files there? Files should not be attached to public mailing list messages as it puts a large amount of strain on the infrastructure, not only with the mail

Hi Atul, Again continuing from Troels' post at http://thread.gmane.org/gmane.science.nmr.relax.user/1718/focus=1732. Well, actually, as Troels fully covered all of you questions in more detail than I could have provided, I don't have anything to add. If you have other questions, please don't

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 Atul. Please use the support tracker when you upload files. The email list is fragile, and cannot handle email attachment. I made small modifications to your script. I normally split them up. 1st script for setup, and printing stuff to check. 2nd script, which just call the previous

Dear Atul. Thank you for a very descriptive problem. I am sure this post will help others. I will write an extended detailed description, in hope it can help others. Most of it will be trivial for you. Let us arm ourself with some reference information, to let the details become clearer. Since

Dear Edward, I already mentioned the issue but I realized that perhaps the question was not very clear. Following is the situation I am trying to solve by 'relax': I have constant-relaxation-time relaxation-dispersion data for off-resonance 15N R1rho acquired on Bruker spectrometers (I would

Hi Atul, I have just returned from holidays, hence my late reply. However Troels' reply should have fully addressed your questions and issues. Is the analysis now working for you? Note that the spin-lock amplitude Omega_1 is the spin-lock field strength or nu_1, as you have supplied (converted

Dear Atul. Welcome to the mailing list! This question is a very good one, and is not covered good enough in the manual ! There has been a question related to this question on the mailing list recently. From Peixiang, at: http://thread.gmane.org/gmane.science.nmr.relax.user/1654

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:
