Chemical Shift Mapping - cmb - 10-21-2019

Hey,

for some reason, when I do the chemical shift mapping, it doesnt adjust the color code to the graph. It plots everything in the disappeared peaks color. This happened in my HN spectra but not with my NCAs, and also not in the tutorial data. All the settings for th CSM (e.g threshold) are the same. What could be the problem?

Thanks in advance.

Hi,
I noticed the same. I got the colors back after removing all but H, N, and side chain NH-group atoms from the NmrChains, NC:A - mimicking the atom list in the Tstar tutorial. Not very practical, though, and in your case, would not allow for plotting other type of data anymore.

Hi, it could be related to the Axis codes in different spectra, non compatible nmrAtoms or most probably including spectra which don't have all the same assigned peaks. Are you able to share the projects? Even as NEF files. Thanks
