Update of sr #2336 (project relax): Assigned to: None => semor _______________________________________________________ Follow-up Comment #1: Hi, Welcome to relax. Here are a few tips that should help you solve your problem. But first, what relax version do you use (1.2, 1.3 ; release, repository) ? 1. The function 'relax_fit.read()' doesn't exist. 2. If you want to read in a NMRView peak list, of course you would like to avoid an argument such as 'format=sparky'. However, since the function you used is incorrect, this is not important now. 3. If you would like to read peak intensities in the purpose of fitting R1 or R2, I would propose you look at the following sample script: 'sample_scripts/relax_fit.py'. It contains an example on how to use the function 'spectrum.read_intensities()' to read in intensities from peak lists. 4. Finally, for further details on the functions in that sample script, I would suggest you look in relax manual, which can either be obtained on relax website (http://www.nmr-relax.com) or by compiling it directly on your system using: 'scons user_manual_pdf'. Good luck !
