Hi, I ran a 3D HNN experiment. After running the conversion from Bruker through NMRpipe, I ended up with axes of H, N, and N. However, when I read the file in sparky, I am getting axes H, H, H although the chemical shift is clearly correct for 15N. Is there any way I can change these axes to the correct H, N, N? It is messing up my peak picking.
