The spin graph assigner (ga) will use your side chain carbon resonance
assignments obtained from cch-tocsy or by any other means. I suspect it
is not working for you because Sparky is confused about which proton
axis of the hcch-tocsy is attached to the carbon on the carbon axis.
You can tell Sparky which proton axis is attached to the carbon using
Extensions / Spectrum / Spectrum labelled axis (la). I suspect you will
see that Sparky has guessed incorrectly which axis has the attached
proton when you use la.
