1707	Set atom types for residue based on dictionary	Tristan Croll	Eric Pettersen	"AddH is getting things wrong for the modified nucleobase 1MG in 6hrm (partially because the starting geometry is a little wonky):

 - O6 is treated as single-bonded (actually double)
 - the ribose is treated like an aromatic ring (to be fair, the geometry *is* somewhat too close to planar, and the chirality is wrong at O2')

In cases like this, it would be great to have the option to add hydrogens strictly according to the CCD definition of the residue."	enhancement	closed	moderate		Structure Editing		fixed						all	ChimeraX
