AMBER: types of water atom

   When I want to use the amber94 force field I found that there are two
types of atoms for water atoms. For example, for the oxygen, these are OW
and OT. These two kind of oxygen differs in their charge. In the
article "A second generation Force Field.." says that OW is the oxygen
of TIP3P model, in the force field this oxygen is a OT(OW is another
oxygen for water).
Which should I use to run a dynamic?

Thanks in advance
