Remark: if I change that dihedral with -CH CH2 CH CB gd_17,
that it gives again 2 9 10 11 , but this time with gd_17, as it should do. But why it does not work with the other definition? Does it have to do with the fact that in the dihedral I have atoms belonging to 3 residues? And are the 2 definitions (with +CH2 and CB at the end) equivalent, taking in acount that we define also an improper of type gi_2 around the CH atom?
