Do I understand correctly that there is no way to force refine to skip the serial in the output pdb file name, i.e. foo.pdb, not foo_001.pdb?Yes, that's true. The main reason is that the same run writes foo_001.eff foo_002.def When I implemented this I thought the serial numbers are the only practical way to keep things straight. Later we added storage of refined f' and f" to the .def file (since there is no place in the .pdb file that would survive passes through external programs). Because of this the serial numbers seem even more important to me.
