[Chimera-users] hydrogen bond in proteins

Of course the hydrogen bonds are always to the hydrogen atom -- the difference is only how the lines are drawn. Many structures do not include the hydrogens, so it makes sense to draw the line from the donor heavy atom to the acceptor heavy atom. However, we recently made a change that if your structure does include hydrogens, the lines will be drawn to the hydrogens instead.
This is only in the newest versions, not the 1.4.1 production release. You would need to get a "daily build" download, Chimera version 1.5, to see this change.
I hope this helps,
