Maybe running the network anchoring with a Low seq strictness (i.e. using any network support) would find at least some of these multiple contributions. ;-) > I would therefore like to deassign F2 for all peaks in my carbon NOESY > and start again (my initial peak list contained hardly any F2 > assignments anyway). What is the best and easiest way to do this? There isn't really a good way. So, your script was the most elegant solution at present. A function to clean assignments in only one dim probably ought to be in Analysis. Now on my list.
