Hi, No, I have not had a chance to try this software. Which specific package did you mean though? None of the softwares E-SpiReS, C++OPPS, or DITE from their basic descriptions are for the analysis of standard NMR relaxation data using SRLS theory. Maybe I would need to do some more research into what the program is called. For comparing relax to their SRLS program, what exactly do you mean? Would you like a measure of which theory is better, model-free vs. SRLS. Or which fits better, which is theoretically better, or how one approximates the other? relax does not have SRLS implemented yet - the foundations for adding this analysis type has been laid for anyone interested in adding this - so comparing how good the implementation of SRLS theory is between different programs to relax is not yet possible.

Hi Edward. Polimeno has a new version of the SRLS available for download. http://www.chimica.unipd.it/licc/ Did you tried to compare? Boaz
