Follow-up Comment #11, sr #2336 (project relax): Hi Ryan. Thanks for the reply. It is a 600MHz spec. There are 2 duplicates for T1 and T1rho data. T1rho is very similar to T2, and can be converted to T2 easily. The replicates are fairly similar. If I look at the data using intensities, and fit to 2 param exponential in matlab, 200 monte carlos, the error is much smaller. I am unsure why there is a discrepancy using relax. I am just using nmrview peaklists, and the relax sample script to process the data. _______________________________________________________ Reply to this item at: <http://gna.org/support/?2336> _______________________________________________ Message sent via/by Gna! http://gna.org/
