Follow-up Comment #4, sr #2336 (project relax): Thanks for the help. It now works! However, I am having trouble with the error values. The SDev for the noise in the spectra from nmrview is 0.0. However, if I use the RMSD function in sparky to get noise values, the errors on the plotted figures from relax are 4 orders of magnitude bigger than the actual data. I know that the data is of fairly high quality. What is the best method for estimating errors for relax? Thanks. _______________________________________________________ Reply to this item at: <http://gna.org/support/?2336> _______________________________________________ Message sent via/by Gna! http://gna.org/
