Hello,

It's a Sparky beginner. I wanted to make a nice picture with protein assignment but for all assigned residues I have the name format as ex. L166N-HN and I want to avoid "N-HN". I have found in Sparky manual that:

Display format for assignment labels

The assignment format specifies how to display assignment labels on contoured spectra. The default format is "%a1-%a2" for a 2-D spectrum. The "%a1" means display the full atom name for the w1 assignment. The full atom name includes the group. Then the "-" is just put into the label. Then "%a2" means display the atom name for the w2 assignment. The "%a2" will not display the group if it is the same as the group displayed in the preceding "%a1" part. To force the groups to be displayed use "%A1-%A2". In general, "%a" means display the atom name and leave off the group name if the preceding % format displayed the group, whereas "%A" means always show the full atom name. To show just the group names use "%G1-%G2". To show just the group name for the w2 axis use "%G2".

So I've changed the assignment format for %G2, but nothing changed in my spectrum, although peak list changed. I also tried to save the new peak list and upload it again, but then I have problems with unreadable lines..
