[Chimera-users] sulfone

I am trying to assign charges to a compound that contains a sulfone group. The charge assignment depends upon how I name the atoms. The atom assignment for the oxygens that are part of the sulfone group and the sulfur itself vary depending upon how they are named. How should I name them so that they are handled correctly? Barb Truitt PS - I receive the Chimera list emails, but my outgoing email address apparently doesn't match the one that I used to sign up for the list. Is there a way to fix that?
